He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.'" They said, "Now you have come with the truth." So they slaughtered her, but they could hardly do it.

Grammar, phrase by phrase
قَالَ
(He said,)
Root قول — to say, speak, tell · 1,722 times in the Quran
قَالَword 1
Verb · فعلA verb is a word for an action tied to a time. قَالَ names an action — saying — from the root قول, to say, speak, tell. L1 · R7
Past Tense Verb · فعل ماضٍA past tense verb describes an action already completed; its base shape is the 'he' form with no ending added. قَالَ is that bare base shape: 'he said' — Musa answering them. L8 · R1
Weak Verb · فعل معتلA weak verb has و or ي among its root letters, and a middle weak letter hides behind a long alif in the past tense. قَالَ is the root قول — the long ا in its middle is the weak و in disguise. L24 · R4
إِنَّهُۥ يَقُولُ إِنَّهَا بَقَرَةٌۭ
(…"He says, 'It is a cow)
Root قول — to say, speak, tell · 1,722 times in the Quran
Root بقر — cow, cattle · 9 times in the Quran
إِنَّهُۥword 2
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 'he' ending fused onto 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 is such a suffix, standing for 'He' — the Lord whose words Musa now relays. L3 · R6
يَقُولُword 3
Verb · فعلA verb is a word for an action tied to a time. يَقُولُ names an action — saying — from the root قول: to say, speak, tell. L1 · R7
Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. يَقُولُ opens with the letter يَ — the 'he' prefix — standing before the root letters: 'He says'. L8 · R3
Weak Verb · فعل معتلA weak verb has و or ي among its root letters, hidden in some shapes and revealed in others: the past قَالَ hides its middle letter behind a long alif, and the present tense reveals it. يَقُولُ shows that true middle letter و of the root قول in plain view. L24 · R4
إِنَّهَاword 4
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 is the 'she' ending fused onto 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 is such a suffix, standing for 'her' — the cow, spoken of as 'she'. L3 · R6
بَقَرَةٌۭword 5
Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـٌ — is a noun, a naming word. بَقَرَةٌ names a cow, from the root بقر — cow, cattle. L1 · R2
Feminine Noun · اسم مؤنثA feminine noun is a naming word Arabic treats as grammatically 'she', typically marked by a ة at its end. بَقَرَةٌ wears exactly that ة before its final tanwīn: 'a cow'. L2 · R1
Indefinite Noun · نكرةAn indefinite noun means 'a' or 'any' one — no particular one — and shows this with tanwīn, the doubled end-vowel mark. بَقَرَةٌ ends in the doubled ḍammah ـٌ: 'A cow', still being narrowed down. L2 · R8
Nominative · مرفوعThe nominative is an ending shown by a ḍammah ـُ — a small curl above the last letter — or its doubled form ـٌ, worn by the subject or the completing part of a sentence. بَقَرَةٌ ends in that doubled ḍammah ـٌ: it is the completing part of 'indeed it [is]…', which keeps its own nominative form while إِنَّ presses only its topic. L2 · R10
لَّا ذَلُولٌۭ تُثِيرُ ٱلْأَرْضَ
(…neither trained to plow the earth)
Root ذلل — to humble, subdue; humiliation, lowliness · 24 times in the Quran
Root ثور — to rise, bull, ox · 5 times in the Quran
Root ارض — earth, land, ground · 461 times in the Quran
لَّاword 6
Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. لَّا is such a helper word. L1 · R8
Negation Particle · حرف نفيA negation particle flips a statement to its opposite, and لَا is the one used for general statements. Here it denies a quality of the cow: NOT trained. L4 · R5
ذَلُولٌۭword 7
Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـٌ — is a noun, a naming word. ذَلُولٌ names a quality — trained, broken in — from the root ذلل: to humble, subdue; humiliation, lowliness. L1 · R2
Indefinite Noun · نكرةAn indefinite noun means 'a' or 'any' one — no particular one — and shows this with tanwīn, the doubled end-vowel mark. ذَلُولٌ ends in the doubled ḍammah ـٌ, matching the 'a cow' it describes. L2 · R8
Nominative · مرفوعThe nominative is an ending shown by a ḍammah ـُ — a small curl above the last letter — or its doubled form ـٌ. ذَلُولٌ ends in that doubled ḍammah ـٌ, copying the nominative of بَقَرَةٌ, the word it describes. L2 · R10
Adjective · صفةAn adjective is a describing word that comes after its naming word — the opposite of English order. ذَلُولٌ follows بَقَرَةٌ 'a cow' and copies its ending: both carry the doubled ḍammah ـٌ, indefinite and nominative alike — 'a cow not trained'. L7 · R1
تُثِيرُword 8
Verb · فعلA verb is a word for an action tied to a time. تُثِيرُ names an action — ploughing, turning up — from the root ثور: to rise, bull, ox. L1 · R7
Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. تُثِيرُ opens with the letter تُ — the prefix used for 'she', the cow — standing before the root letters: 'she ploughs'. L8 · R3
Weak Verb · فعل معتلA weak verb has at least one of the weak letters و or ي among its root letters, and the subtype is named by which slot is weak — a weak middle letter makes the hollow type. The root ثور carries the weak و in its middle slot; in this word it does not show as و but as the long ي of تُثِيرُ. L24 · R4
Form IV Verb · أَفْعَلَA Form IV verb adds a hamzah to the front of its past shape, and in the present tense this family is identified by a ḍammah ـُ — a small curl — on the prefix letter. تُثِيرُ shows exactly that: its opening تُ carries the ḍammah ـُ, the present-tense signature of this form. L12 · R7
ٱلْأَرْضَword 9
Definite Article · أل التعريفThe definite article is the prefix ال attached to the front of a naming word to mean 'the' — one specific, known one. ٱلْأَرْضَ wears that prefix, and its ل keeps its own sound, written with the sukūn ـْ — the small circle meaning no vowel follows: al-arḍ, 'the earth'. L2 · R9
Noun · اسمA word that accepts ال — the prefix meaning 'the' — is a noun, a naming word. أَرْضَ names the earth, from the root ارض — earth, land, ground. L1 · R1
Feminine Noun · اسم مؤنثSome naming words are grammatically 'she' — feminine — without any visible marker, and must simply be known; أَرْض 'earth' is one of these special feminine words. L2 · R2
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 last letter. أَرْضَ ends in exactly that fathah ـَ. L2 · R11
Direct Object · مفعول بهThe direct object is the thing the action lands on, standing in the accusative — the landed-on form, here the fathah ـَ on the ض. 'The earth' is what the ploughing would land on — and this cow does no such work. L9 · R3
"It is a cow neither trained to till the soil nor water the fields" means it is not used in farming or for watering purposes; rather, it is honorable and fair looking.
Ibn Kathir (abridged), on 2:68–71
وَلَا تَسْقِى ٱلْحَرْثَ
(…nor to irrigate the field,)
Root سقي — to give to drink, to water, to irrigate · 25 times in the Quran
Root حرث — tilth, to till and sow the ground · 14 times in the Quran
وَلَاword 10
Conjunction · حرف عطفA conjunction is a particle that joins words or sentences. The prefix وَ 'and' joins the second denied quality to the first: neither ploughing NOR watering. L4 · R4
Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. لَا is such a helper word. L1 · R8
Negation Particle · حرف نفيA negation particle flips a statement to its opposite, and لَا is the one used for general statements. Here it repeats the denial: she does NOT water the field. L4 · R5
تَسْقِىword 11
Verb · فعلA verb is a word for an action tied to a time. تَسْقِى names an action — watering — from the root سقي: to give to drink, to water, to irrigate. L1 · R7
Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. تَسْقِى opens with the letter تَ — the prefix used for 'she', the cow — standing before the root letters: 'she waters'. L8 · R3
Weak Verb · فعل معتلA weak verb has و or ي among its root letters; when the weak letter is the LAST root letter, the verb is the defective type, surfacing as a final long vowel. تَسْقِى is the root سقي — its final weak letter surfaces as the ى closing the word. L24 · R7
ٱلْحَرْثَword 12
Definite Article · أل التعريفThe definite article is the prefix ال attached to the front of a naming word to mean 'the' — one specific, known one. ٱلْحَرْثَ wears that prefix, and its ل keeps its own sound, written with the sukūn ـْ — the small circle meaning no vowel follows: al-ḥarth, 'the field'. L2 · R9
Noun · اسمA word that accepts ال — the prefix meaning 'the' — is a noun, a naming word. حَرْثَ names the tilled field, from the root حرث — tilth, to till and sow the ground. L1 · R1
Masculine Noun · اسم مذكرArabic treats every naming word as grammatically 'he' or 'she'. This word carries no feminine marker such as a ة at its end, so it falls to 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 last letter. حَرْثَ ends in exactly that fathah ـَ. L2 · R11
Direct Object · مفعول بهThe direct object is the thing the action lands on, standing in the accusative — the landed-on form, here the fathah ـَ on the ث. 'The field' is what the watering would land on — work this cow was never put to. L9 · R3
مُسَلَّمَةٌۭ
(…one free from fault)
Root سلم — to submit, surrender; peace, Islam · 140 times in the Quran
مُسَلَّمَةٌۭword 13
Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـٌ — is a noun, a naming word. مُسَلَّمَةٌ names a quality — sound, free from fault — from the root سلم: to submit, surrender; peace. L1 · R2
Indefinite Noun · نكرةAn indefinite noun means 'a' or 'any' one — no particular one — and shows this with tanwīn, the doubled end-vowel mark. مُسَلَّمَةٌ ends in the doubled ḍammah ـٌ, matching the 'a cow' it describes. L2 · R8
Nominative · مرفوعThe nominative is an ending shown by a ḍammah ـُ — a small curl above the last letter — or its doubled form ـٌ. مُسَلَّمَةٌ ends in that doubled ḍammah ـٌ, copying the nominative of بَقَرَةٌ, the word it describes. L2 · R10
Adjective · صفةAn adjective is a describing word that comes after its naming word — the opposite of English order. مُسَلَّمَةٌ describes the same بَقَرَةٌ 'a cow' and copies its ending: both carry the doubled ḍammah ـٌ, indefinite and nominative alike — 'a cow… free from fault'. L7 · R1
Passive Participle · اسم مفعولA passive participle is a naming word built from a verb's root for the one the action was done to; for the derived verb families it begins with مُـ and carries a fathah ـَ — a small slanted stroke above — before its last root letter. مُسَلَّمَةٌ shows that مُ at its front and the fathah ـَ before its last root letter م: one rendered sound, kept whole. L11 · R3
"Sound" means the cow does not suffer from any defects — as Qatadah, Abu Al-'Aliyah, Ar-Rabi' and Mujahid said, it is free from defects.
Ibn Kathir (abridged), on 2:68–71
لَّا شِيَةَ فِيهَا ۚ
(…with no spot upon her.'")
Root وشي — to embellish, to adorn · 1 times in the Quran
لَّاword 14
Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. لَّا is such a helper word. L1 · R8
Negation Particle · حرف نفيA negation particle flips a statement to its opposite. This لَا denies a whole category at once — 'there is NO spot at all' — and the naming word right after it, شِيَةَ, wears the fathah ـَ, the small slanted stroke above its last letter, that this لَا places on it. L4 · R7
شِيَةَword 15
Noun · اسمA word ending with the ة — Tā Marbūtah — is a noun, a naming word. شِيَةَ names a spot or blemish, from the root وشي: to embellish, to adorn. L1 · R3
Feminine Noun · اسم مؤنثA feminine noun is a naming word Arabic treats as grammatically 'she', typically marked by a ة at its end. شِيَةَ wears exactly that ة as its final letter. L2 · R1
Accusative · منصوبThe accusative is an ending shown by a fathah ـَ — a small slanted stroke above the last letter — taken by a naming word after certain particles. شِيَةَ ends in a single fathah ـَ with no doubling, as the word owned by the category-denying لَا before it: no spot whatsoever. L2 · R11
فِيهَا ۚword 16
Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. فِي is such a helper word. L1 · R8
Preposition · حرف جرA preposition is a little word that relates one thing to another and pulls the naming word after it into the genitive — the after-preposition ending, usually a kasrah ـِ, a small stroke below the last letter. فِي 'in' is one of the common prepositions: no spot 'in her'. L4 · R2
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word; glued to a particle, it is governed by that particle. The ending هَا on فِيهَا stands for 'her' — the cow whose hide bears no spot. L3 · R6
So far: “He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.'"”
قَالُوا۟ ٱلْـَٔـٰنَ جِئْتَ بِٱلْحَقِّ ۚ

Weak Verb · فعل معتلA weak verb has و or ي among its root letters, and a middle weak letter hides behind a long alif in the past tense. قَالُوا۟ is the root قول — the long ا in its middle is the weak و in disguise. L24 · R4

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
ٱلْـَٔـٰنَword 18
Definite Article · أل التعريفThe definite article is the prefix ال attached to the front of a word to mean 'the' — one specific, known one. ٱلْـَٔـٰنَ wears that prefix, and its ل keeps its own sound, written with the sukūn ـْ — the small circle meaning no vowel follows: 'THE now', this very moment. L2 · R9
Accusative · منصوبThe accusative is an ending shown by a fathah ـَ — a small slanted stroke above the last letter. ـَٰٔنَ ends in exactly that fathah ـَ, the ending words of time carry. L2 · R11
Time Adverb · ظرف زمانA time adverb is a naming word that anchors a sentence to the time its action happens, and such time words take the accusative — the fathah ـَ, a small slanted stroke above the last letter. ـَٰٔنَ 'now' wears that fathah, anchoring their words to this very moment: 'NOW you have come with the truth'.

Weak Verb · فعل معتلA weak verb has و or ي among its root letters, and the subtype is named by which slot is weak — a weak middle letter makes the hollow type.

Hamzated Verb · فعل مهموزA hamzated verb has a hamza (ء) among its letters, and the hamza's written seat changes with the surrounding vowels, which can disguise the root. In جِئْتَ the hamza sits on a ي-shaped seat as ئ, capped with the sukūn ـْ — the small circle meaning its sound stops there. L24 · R11
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending تَ on جِئْتَ is such a suffix, standing for 'you' — Musa, being addressed. L3 · R6

فَذَبَحُوهَاword 21

Past Tense Verb · فعل ماضٍA past tense verb describes an action already completed, and who did it is shown by an ending added to the verb. The ending و — the 'they' marker — sits on ذَبَحُ: 'they slaughtered'. L8 · R2
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word — and this one verb carries two: the و standing for 'they', and after it هَا standing for 'her', the cow. One written word packs a whole sentence. 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 و is that doer, 'they'; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4
Direct Object · مفعول بهThe direct object is the one 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 final هَا 'her' is that object, glued straight onto the verb; a pronoun keeps one fixed shape, so the accusative is the role it fills. L9 · R5

Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. مَا is such a helper word. L1 · R8
Negation Particle · حرف نفيA negation particle flips a statement to its opposite, and مَا is the one that negates past-tense statements. Here it denies the nearness: they were NOT near to doing it. L4 · R5
كَادُوا۟word 23
Verb · فعلA verb is a word for a happening tied to a time. كَادُ speaks of nearness to an action — was about to do, was on the point of — from the root كود. L1 · R7
Past Tense Verb · فعل ماضٍA past tense verb describes what is already settled, and who did it is shown by an ending added to the verb. The ending وا۟ — the 'they' marker — sits on كَادُوا۟: 'they were near'. L8 · R2
Weak Verb · فعل معتلA weak verb has و or ي among its root letters, and a middle weak letter hides behind a long alif in the past tense. كَادُوا۟ is the root كود — the long ا in its middle is the weak و in disguise. L24 · R4
Verbs of Proximity (Kāda) · كاد وأخواتهاA verb of proximity says the action was close at hand: كَادَ means 'almost / nearly did', and its completing part is a present tense verb that follows it. كَادُوا۟ stands right before يَفْعَلُونَ 'doing it' — with the 'not' before it: they were hardly, only barely, brought to do it. L18 · R10
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending وا۟ on كَادُوا۟ is such a suffix, standing for 'they' — the ones so near to leaving the command undone. L3 · R6

The Five Verbs · الأفعال الخمسةThe Five Verbs are the five present-tense shapes ending in نَ, where that نَ itself is the mood sign: kept, it marks the normal mood; dropped, it marks a trimmed mood. يَفْعَلُونَ is one of those five shapes, and its نَ is kept — the normal, untrimmed mood. L10 · R10
Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending ونَ on يَفْعَلُونَ is such a suffix, standing for 'they'. 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 ونَ is that doer, 'they'; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4
"So they slaughtered it though they were near to not doing it" means, as Ibn 'Abbas said, "They did not want to slaughter it" — even after all the questions and answers, they were still reluctant; the Qur'an criticized this behavior, for their only goal was to be stubborn.
Ibn Kathir (abridged), on 2:68–71
So far: “He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.'" They said, "Now you have come with the truth." So they slaughtered her, but they could hardly do it.”
