They said, "Call upon your Lord to make clear to us what it is." [Moses] said, "[Allāh] says, 'It is a cow which is neither old nor virgin, but median between that,' so do what you are commanded."

(They said, "Call upon your Lord)
Root قول — to say, speak, tell · 1,722 times in the Quran
Root دعو — to call, invoke, pray to; supplication · 212 times in the Quran
Root ربب — Lord, Sustainer, Nourisher, Regulator, Perfector · 980 times in the Quran
قَالُوا۟word 1
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. قَالُ speaks of an action already carried out: 'They said', from the root قول: to say, speak, tell. L1 · R7
Past Tense Verb · فعل ماضٍA past-tense verb describes an action already completed — and it shows who by a small ending fastened to the verb's tail. On قَالُوا۟ that ending is وا۟, telling exactly who is meant: 'They said', from the root قول: to say, speak, tell. L8 · R2
Weak Verb · فعل معتلA weak verb is a verb that carries و or ي — the 'weak' letters, which love to soften into long vowels or vanish — among its root letters. The root of قَالُ is قول: to say, speak, tell — and its middle letter is the weak و, so the weakness sits in the middle of the root. L24 · R4
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word for 'I / you / he' that cannot stand alone — it is glued onto the end of another word, and each form carries within it exactly who is meant. وا۟ · 'them/their' is fastened to the tail of the verb here — قَالُوا۟ — naming the one who did the action. L3 · R6
Doer (Fa'il) · فاعلThe doer is the one performing the action, standing in the nominative — the doer's form, usually a ḍammah ـُ, a small curl above the last letter. The ending وا۟ is that doer, 'they'; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4
ٱدْعُword 2
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. ٱدْعُ is a command: 'Pray', from the root دعو: to call, invoke, pray to; supplication. L1 · R7
Imperative Verb · فعل أمرAn imperative verb is a direct command addressed to 'you', formed from the present-tense verb by removing its opening prefix and adding a helping ٱ when what remains starts with a vowelless letter. ٱدْعُ shows that helping ٱ at its front — a command to one man, Musa: call! L10 · R1
Weak Verb · فعل معتلA weak verb has و or ي among its root letters, and when the weak letter ends the root it is dropped in the command shape, the short vowel left behind signalling which letter was deleted. ٱدْعُ is that clipped command of the root دعو: its final و is gone, and the ḍammah ـُ — the small curl above the ع — is the fingerprint of the deleted و. L24 · R7
لَنَاword 3
Preposition · حرف جرThe small prefix لَ at the front of لَنَا is a preposition — a little helper word meaning 'to/for' that relates one thing to another. A preposition 'pulls' the word that follows it into the genitive relationship — the 'of / in / with' role a word plays after such a little helper — though not every word shows that role with the same visible ending. L4 · R1
Detached Pronoun · ضمير منفصلA pronoun is a mini-word standing in for a name, here نَا 'us'. Though the label reads it as a standalone word, it is written joined after the preposition لَ and works like the glued-on endings for 'our/us', naming those the prayer is for: 'for us'. L3 · R7
رَبَّكَword 4
Noun · اسمA noun is a word that names a person, place, thing, or idea. رَبَّ names such a thing: '(to) your Lord', from the root ربب: Lord, Sustainer, Nourisher, Regulator, Perfector. L1 · R6
Masculine Noun · اسم مذكرArabic treats every noun — every naming word — as grammatically 'he' or 'she'. رَبَّكَ carries no feminine marker — no ة at its end, no final ى, no اء — so it takes the default and is treated as 'he': a masculine noun. L2 · R3
Accusative · منصوبThe accusative is the ending a naming word takes when the action lands on it, shown by a fathah ـَ — a small slanted stroke above the letter. رَبَّ ends in that fathah ـَ, sitting atop its doubled ب. L2 · R11
Direct Object · مفعول بهThe direct object is the one the action lands on, standing in the accusative — the landed-on form, here the fathah ـَ above the doubled ب. 'Your Lord' is the One the commanded calling is directed to. L9 · R3
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word. The ending كَ on رَبَّكَ is such a suffix, standing for 'your': YOUR Lord. L3 · R6
Possessive (Idafa) · مضاف إليهA possessive (iḍāfah) chains two naming words into an 'of' phrase, and the owner comes second, taking the genitive — the owner's ending, usually a kasrah ـِ, a small stroke below the last letter. The ending كَ fills that owner slot: 'the Lord OF you'; a pronoun keeps one fixed written shape, so the genitive is the role it fills. L5 · R5
Allah mentioned the stubbornness of the Children of Israel and the many unnecessary questions they asked their Messengers; because they were stubborn, Allah made the decisions difficult for them.
Ibn Kathir (abridged), on 2:68–71
يُبَيِّن لَّنَا مَا هِىَ ۚ
(…to make clear to us what it is.")
Root بين — to be between, make clear, evident · 523 times in the Quran
يُبَيِّنword 5
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. يُبَيِّن is an action unfolding now: 'to make clear', from the root بين: to be between, make clear, evident. L1 · R7
Present Tense Verb · فعل مضارعA present-tense verb is the verb shape that opens with one of the four present-tense prefixes أ ن ي ت; small helper words before it can bend its time and mood. يُبَيِّن wears that present-tense shape, opening with exactly such a letter: 'to make clear', from the root بين: to be between, make clear, evident. L8 · R3
Jussive Mood · الفعل المجزومThe jussive is one of the three moods of a present tense verb — the cut-down mood, whose usual mark is the sukūn ـْ, the small circle meaning the sound stops on that letter. يُبَيِّن ends with exactly that stopped, vowelless ن — the cut-short shape — standing as what follows on the asked-for prayer: He will make it clear. L10 · R8
Weak Verb · فعل معتلA weak verb is a verb that carries و or ي — the 'weak' letters, which love to soften into long vowels or vanish — among its root letters. The root of يُبَيِّن is بين: to be between, make clear, evident — and its middle letter is the weak ي, so the weakness sits in the middle of the root. L24 · R4
Form II Verb · فَعَّلَA Form II verb is identified by a shaddah ـّ — the small w-shaped doubling mark — on the second root letter. يُبَيِّن shows that shaddah on the ي in its middle: the mark of this form, here making something clear to others. L12 · R7
لَّنَاword 6
Preposition · حرف جرThe small prefix لَّ at the front of لَّنَا is a preposition — a little helper word meaning 'to/for' that relates one thing to another. A preposition 'pulls' the word that follows it into the genitive relationship — the 'of / in / with' role a word plays after such a little helper — though not every word shows that role with the same visible ending. L4 · R1
Detached Pronoun · ضمير منفصلA pronoun is a mini-word standing in for a name, here نَا 'us'. Though the label reads it as a standalone word, it is written joined after the preposition لَّ and works like the glued-on endings for 'our/us', naming those the clarifying is for: 'to us'. L3 · R7
مَاword 7
Predicate (Khabar) · خبرThe predicate is the part that completes the meaning about the topic, and it stands in the nominative — the completing word's own form, usually a ḍammah ـُ, a small curl above the last letter. The asking word مَا 'what?' is that completing part, brought to the front as questions are: 'it [is] WHAT?'; it keeps one fixed written shape, so the nominative is the role it fills. L6 · R3
Interrogative Particle · حرف استفهامAn interrogative word turns a statement into a question, and مَا 'what?' is one of the specific question words. Here it asks for the cow's description: WHAT is it? L17 · R3
هِىَ ۚword 8
Detached Pronoun · ضمير منفصلA detached pronoun is a standalone word for 'I/you/he/she/they'. هِىَ is the 'she' of that set, standing here for 'it' — the cow, spoken of as 'she'. L3 · R2
Subject (Mubtada') · مبتدأThe subject is the naming word a sentence opens by talking about — its topic — and it stands in the nominative, the topic's form, usually shown by a ḍammah ـُ, a small curl above the last letter. In the little question 'what is it?', هِىَ 'it' is that topic; a pronoun keeps one fixed written shape, so the nominative is the role it fills. L6 · R2
Direct Object · مفعول بهThe direct object is what the action lands on, standing in the accusative — the landed-on form, usually a fathah ـَ, a small slanted stroke above the last letter. The little question 'what it is' is what the making-clear must land on, and هِىَ anchors it; a pronoun keeps one fixed written shape, so the accusative here is the role, not a mark on show. L9 · R3
They said, "Call upon your Lord for us that He may make plain to us what it is" — meaning, "What is this cow, and what is its description?"
Ibn Kathir (abridged), on 2:68–71
So far: “They said, "Call upon your Lord to make clear to us what it is."”
قَالَ إِنَّهُۥ يَقُولُ
(…[Moses] said, "[Allāh] says,)
Root قول — to say, speak, tell · 1,722 times in the Quran
قَالَword 9
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. قَالَ speaks of an action already carried out: 'He said', from the root قول: to say, speak, tell. L1 · R7
Past Tense Verb · فعل ماضٍA past-tense verb describes an action already completed. Its plain base shape — the shape Arabic uses for a single 'he' — carries no who-ending glued to its tail, and قَالَ is exactly that bare base: 'He said', from the root قول: to say, speak, tell. L8 · R1
Weak Verb · فعل معتلA weak verb is a verb that carries و or ي — the 'weak' letters, which love to soften into long vowels or vanish — among its root letters. The root of قَالَ is قول: to say, speak, tell — and its middle letter is the weak و, so the weakness sits in the middle of the root. L24 · R4
إِنَّهُۥword 10
Accusative Particle (إنّ) · حرف مشبه بالفعلإِنَّ adds emphasis — 'indeed' — and changes the topic it introduces from the nominative to the accusative, the pressed-on form, usually a fathah ـَ, a small slanted stroke above the last letter. إِنَّ carries its doubling shaddah ـّ — the small w-shaped mark — and its topic here is the هُۥ glued to it: 'indeed HE says'. L15 · R2
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word. The ending هُۥ on إِنَّهُۥ stands for 'He' — Allah — the topic إِنَّ presses into the accusative, the pressed-on form, usually a fathah ـَ, a small stroke above the last letter; a pronoun keeps one fixed written shape, so the accusative is the role it fills. L3 · R6
يَقُولُword 11
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. يَقُولُ is an action unfolding now: 'says', from the root قول: to say, speak, tell. L1 · R7
Present Tense Verb · فعل مضارعA present-tense verb describes an action happening now or still to come, and it is recognized by its opening letter — one of the four present-tense prefixes أ ن ي ت. يَقُولُ opens with exactly such a letter: 'says', from the root قول: to say, speak, tell. L8 · R3
Weak Verb · فعل معتلA weak verb is a verb that carries و or ي — the 'weak' letters, which love to soften into long vowels or vanish — among its root letters. The root of يَقُولُ is قول: to say, speak, tell — and its middle letter is the weak و, so the weakness sits in the middle of the root. L24 · R4
إِنَّهَا بَقَرَةٌۭ
(…'It is a cow)
Root بقر — cow, cattle · 9 times in the Quran
إِنَّهَاword 12
Accusative Particle (إنّ) · حرف مشبه بالفعلإِنَّ adds emphasis — 'indeed' — and changes the topic it introduces from the nominative to the accusative, the pressed-on form, usually a fathah ـَ, a small slanted stroke above the last letter, while the completing part stays in its own form. إِنَّ carries its doubling shaddah ـّ — the small w-shaped mark — and its topic here is the هَا glued to it: 'indeed IT is a cow…'. L15 · R2
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word. The ending هَا on إِنَّهَا stands for 'it' — the cow, spoken of as 'she' — the topic إِنَّ presses into the accusative, usually a fathah ـَ, a small stroke above the last letter; a pronoun keeps one fixed written shape, so the accusative is the role it fills. L3 · R6
بَقَرَةٌۭword 13
Noun · اسمA word that ends with the tā marbūtah ة is a noun, a naming word. بَقَرَةٌ names a cow, from the root بقر — cow, cattle. L1 · R3
Feminine Noun · اسم مؤنثA feminine noun is a naming word Arabic treats as grammatically 'she', most often marked by a ة — the round 'tied tā' — at its end. بَقَرَةٌ carries exactly that round ة at its end, so it is treated as feminine: '(is) a cow'. L2 · R1
Indefinite Noun · نكرةAn indefinite noun is a naming word left general — not pinned to one known thing by the definite article ال ('the') — and it shows this with tanwīn, a doubled end-vowel mark. بَقَرَةٌ carries the tanwīn ـٌ — the ḍammah ـُ doubled: '(is) a cow'. L2 · R8
Nominative · مرفوعThe nominative is the ending marked by a ḍammah ـُ — a small curl above the last letter, doubled to tanwīn ـٌ when the word is indefinite — that a naming word takes as the subject or predicate of its sentence. بَقَرَةٌ wears that doubled ḍammah ـٌ: it is the completing part telling what 'it' is, and while إِنَّ presses its topic, this completing part keeps its own nominative form. L2 · R10
لَّا فَارِضٌۭ وَلَا بِكْرٌ
(…which is neither old nor virgin,)
Root فرض — to ordain, enact a law, estimate, conceive, to apportion, to impose · 18 times in the Quran
Root بكر — early, first, virgin, morning · 12 times in the Quran
لَّاword 14
Particle · حرفA particle is a small helper word of one to three letters that works like glue — it connects or adjusts other words rather than naming something or describing an action, and it can never be the one a sentence is about. لَّا · 'not/no' is such a helper. L1 · R9
Negation Particle · حرف نفيA negation particle flips a statement to its opposite, and لَا is the one for general statements: 'no / not'. Here it opens the pair 'neither… nor…': NOT old. L4 · R5
فَارِضٌۭword 15
Noun · اسمA noun is a word that names a person, place, thing, or idea. فَارِضٌ names such a thing: 'old', from the root فرض: to ordain, enact a law, estimate, conceive, to apportion, to impose. L1 · R6
Indefinite Noun · نكرةAn indefinite noun is a naming word left general — not pinned to one known thing by the definite article ال ('the') — and it shows this with tanwīn, a doubled end-vowel mark. فَارِضٌ carries the tanwīn ـٌ — the ḍammah ـُ doubled: 'old'. L2 · R8
Nominative · مرفوعThe nominative is an ending marked by a ḍammah ـُ — a small curl above the last letter, doubled to tanwīn ـٌ when the word is indefinite. فَارِضٌ wears that doubled ḍammah ـٌ, the same ending as بَقَرَةٌ, the cow-word it describes. L2 · R10
Adjective · صفةAn adjective is a describing word that comes after its noun and copies its noun's endings. فَارِضٌ 'old' follows بَقَرَةٌ 'a cow' and copies what shows on it: the same doubled ḍammah ـٌ and the same unspecific tanwīn — 'a cow… not an OLD one'. L7 · R1
Active Participle · اسم فاعلAn active participle is a naming word built on the pattern فَاعِل — first root letter, then a long ā, then a kasrah ـِ before the last root letter — naming the one in the action's state. فَارِضٌ carries that shape: the long ا after its ف and the kasrah on its ر — 'one grown old'. L11 · R1
وَلَاword 16
Conjunction · حرف عطفThe prefix وَ at the front of وَلَا is a conjunction — a small joining word meaning 'and' — linking what follows to what came before; the word it joins in must stand in the same grammatical case as its partner before the joint — the same role in the sentence, even when the two words write that case with different endings. L4 · R4
Particle · حرفA particle is a small helper word of one to three letters that works like glue — it connects or adjusts other words rather than naming something or describing an action, and it can never be the one a sentence is about. لَا · 'not/no' is such a helper. L1 · R9
Negation Particle · حرف نفيA negation particle flips a statement to its opposite, and لَا is the one for general statements: 'no / not'. Here it denies the second extreme: NOR a young one. L4 · R5
بِكْرٌword 17
Noun · اسمA noun is a word that names a person, place, thing, or idea. بِكْرٌ names such a thing: 'young', from the root بكر: early, first, virgin, morning. L1 · R6
Indefinite Noun · نكرةAn indefinite noun is a naming word left general — not pinned to one known thing by the definite article ال ('the') — and it shows this with tanwīn, a doubled end-vowel mark. بِكْرٌ carries the tanwīn ـٌ — the ḍammah ـُ doubled: 'young'. L2 · R8
Nominative · مرفوعThe nominative is an ending marked by a ḍammah ـُ — a small curl above the last letter, doubled to tanwīn ـٌ when the word is indefinite. بِكْرٌ wears that doubled ḍammah ـٌ, the same ending as فَارِضٌ, the word it is joined to by وَ. L2 · R10
"Neither too old nor too young" means that it is neither old nor below the age of breeding — the opinion of Abu Al-'Aliyah, As-Suddi, Mujahid, Ibn 'Abbas and others.
Ibn Kathir (abridged), on 2:68–71
عَوَانٌۢ بَيْنَ ذَٰلِكَ ۖ
(…but median between that,')
Root عون — to aid, assist, help · 11 times in the Quran
Root بين — to be between, make clear, evident · 523 times in the Quran
عَوَانٌۢword 18
Noun · اسمA noun is a word that names a person, place, thing, or idea. عَوَانٌۢ names such a thing: 'middle aged', from the root عون: to aid, assist, help. L1 · R6
Masculine Noun · اسم مذكرArabic treats every noun — every naming word — as grammatically 'he' or 'she'. عَوَانٌۢ carries no feminine marker — no ة at its end, no final ى, no اء — so it takes the default and is treated as 'he': a masculine noun. L2 · R3
Singular Noun · مفردA singular noun refers to one entity and shows its case with a single short vowel mark, doubled to tanwīn when the noun is indefinite. عَوَانٌۢ speaks of one — the one middle-aged cow — and wears exactly that doubled mark ـٌ. L2 · R4
Indefinite Noun · نكرةAn indefinite noun is a naming word left general — not pinned to one known thing by the definite article ال ('the') — and it shows this with tanwīn, a doubled end-vowel mark. عَوَانٌۢ carries the tanwīn ـٌ — the ḍammah ـُ doubled: 'middle aged'. L2 · R8
Nominative · مرفوعThe nominative is an ending marked by a ḍammah ـُ — a small curl above the last letter, doubled to tanwīn ـٌ when the word is indefinite — that a naming word takes as the subject or predicate of its sentence. عَوَانٌۢ wears that doubled ḍammah ـٌ. L2 · R10
Predicate (Khabar) · خبرThe predicate completes the meaning about the topic; it too stands in the nominative, and it is typically an unspecific single word. عَوَانٌۢ fits exactly: one word wearing the doubled ḍammah ـٌ, telling more about the cow — 'middle-aged, between that'. L6 · R3
بَيْنَword 19
Accusative · منصوبThe accusative is an ending shown by a fathah ـَ — a small slanted stroke above the letter. بَيْنَ ends in exactly that fathah ـَ — the fixed ending this where-word always wears. L2 · R11
Place Adverb · ظرف مكانA place adverb is a naming word, fixed in the accusative with its fathah ـَ — a small stroke above the last letter — that tells where something stands. بَيْنَ 'between' is one of the high-frequency ones, chained to the word after it: 'BETWEEN that' — between the two extremes just named. L26 · R2
ذَٰلِكَ ۖword 20
Demonstrative Pronoun · اسم إشارةA demonstrative pronoun is a pointing word that singles out a specific thing, near or far. ذَٰلِكَ points to something far: 'THAT' — the old age and the young age just mentioned. L3 · R8
Possessive (Idafa) · مضاف إليهA possessive (iḍāfah) chains two naming words into an 'of' phrase, and the owner comes second, taking the genitive — the owner's ending, usually a kasrah ـِ, a small stroke below the last letter. ذَٰلِكَ fills that owner slot after the where-word بَيْنَ: 'the between OF that'; a pointing word keeps one fixed written shape, so the genitive is the role it fills. L5 · R5
Ibn 'Abbas said "between the two conditions" means: neither old nor young — rather, she was at the age when the cow is strongest and fittest.
Ibn Kathir (abridged), on 2:68–71
فَٱفْعَلُوا۟ مَا تُؤْمَرُونَ
(…so do what you are commanded.")
Root فعل — doing · 108 times in the Quran
Root امر — matter, affair, command · 248 times in the Quran
فَٱفْعَلُوا۟word 21
Resumptive Particle · حرف استئنافA resumptive particle is a وَ or فَ that begins a fresh statement after a pause or a shift of topic — it starts the speech anew rather than adding one more item to a list. The prefix فَ · 'then' at the front of فَٱفْعَلُوا۟ opens such a fresh start. L14 · R1
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. ٱفْعَلُ is a command: 'so do', from the root فعل: doing. L1 · R7
Imperative Verb · فعل أمرAn imperative verb is a direct command addressed to 'you', formed from the present-tense verb by removing its opening prefix and adding a helping ٱ when what remains starts with a vowelless letter. ٱفْعَلُوا۟ shows that helping ٱ at its front, commanding a group — the ending وا۟ points the order at 'you all': do! L10 · R1
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word for 'I / you / he' that cannot stand alone — it is glued onto the end of another word, and each form carries within it exactly who is meant. وا۟ · 'you all/your' is fastened to the tail of the verb here — فَٱفْعَلُوا۟ — naming the one who did the action. L3 · R6
Doer (Fa'il) · فاعلThe doer is the one performing the action, standing in the nominative — the doer's form, usually a ḍammah ـُ, a small curl above the last letter. The ending وا۟ is that doer, 'you all' — the ones told to obey; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4
مَاword 22
Relative Pronoun · اسم موصولA relative pronoun is a word that hooks a whole describing sentence onto its meaning. مَا · 'what' is the relative word Arabic uses for non-human things — 'what' or 'that which' — one fixed shape for any gender and any number: its ending never changes to show its job in the sentence. L5 · R13
Direct Object · مفعول بهThe direct object is the thing the action lands on, standing in the accusative — the landed-on form, usually a fathah ـَ, a small slanted stroke above the last letter. 'What you are commanded' is what the doing must land on; مَا keeps one fixed written shape, so no fathah appears — the accusative is the role it fills. L9 · R3
تُؤْمَرُونَword 23
Verb · فعلA verb is a word for an action or happening that is always tied to a time — past, present/future, or a command. تُؤْمَرُ is an action unfolding now: 'you are commanded', from the root امر: matter, affair, command. L1 · R7
Present Tense Verb · فعل مضارعA present-tense verb describes an action happening now or still to come, and it is recognized by its opening letter — one of the four present-tense prefixes أ ن ي ت. تُؤْمَرُ opens with exactly such a letter: 'you are commanded', from the root امر: matter, affair, command. L8 · R3
The Five Verbs · الأفعال الخمسةThe Five Verbs are the five present-tense shapes whose ending closes with the letter ن — يَفْعَلَانِ, تَفْعَلَانِ, يَفْعَلُونَ, تَفْعَلُونَ, تَفْعَلِينَ. تُؤْمَرُونَ is one of them: its ending ونَ keeps that closing ن, and for these five shapes the kept ن is itself the grammar-sign that the verb stands in its plain, ordinary mood. L10 · R10
Hamzated Verb · فعل مهموزA hamzated verb has a hamza (ء) as one of its root letters, and its written seat changes with the surrounding vowels. The root امر carries the hamza as its first letter; in تُؤْمَرُونَ it sits on a wāw seat — the ؤْ — wearing the sukūn ـْ, the small circle meaning no vowel follows. L24 · R11
Passive Voice · المبني للمجهولA passive voice verb hides who did the action by changing its inner vowels: in the present tense the pattern is a ḍammah ـُ — a small curl — on the prefix and a fathah ـَ on the second root vowel. تُؤْمَرُونَ shows exactly that: the ḍammah on its opening تُ and the fathah on the مَ. The commander is left unnamed; you all are the ones the commanding falls upon. L11 · R4
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending ونَ on تُؤْمَرُونَ is such a suffix, standing for 'you all'. L3 · R6
Passive Subject · نائب فاعلThe passive subject is the one the action happened to, promoted into the subject spot of a verb whose doer is hidden, and it takes the nominative — the subject's form, usually a ḍammah ـُ, a small curl above the last letter. The ending ونَ is that passive subject, 'you all' — the ones being commanded; a pronoun keeps one fixed shape, so the nominative is the role it fills. L11 · R5
So far: “They said, "Call upon your Lord to make clear to us what it is." [Moses] said, "[Allāh] says, 'It is a cow which is neither old nor virgin, but median between that,' so do what you are commanded."”
