Al-Baqarah · 2:79

Grammar — lesson evidence

فَوَيْلٌۭword 1

Resumptive Particle · حرف استئنافA resumptive particle is a وَ or فَ that begins a fresh statement after a pause or shift. The prefix فَ here opens the sentence of doom that follows from what came before. L14 · R1

Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـٌ — is a noun, a naming word. وَيْلٌ names woe — ruin itself, as a thing. L1 · R2

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

Indefinite Noun · نكرةAn indefinite noun is general — not one named instance — and is marked by tanwīn, the doubled end-vowel. وَيْلٌ ends in the doubled ḍammah ـٌ: woe, unbounded by any 'the'. L2 · R8

Nominative · مرفوعThe nominative is the ending a naming word takes as the subject or main topic of a sentence, shown by a ḍammah ـُ — a small curl above the last letter — or its doubled form ـٌ. وَيْلٌ ends in that doubled ḍammah ـٌ. L2 · R10

Subject (Mubtada') · مبتدأThe subject is the naming word a sentence opens by talking about — its topic — standing in the nominative, shown here by the doubled ḍammah ـٌ on وَيْلٌ. 'Woe' is the topic, and the 'to those who…' phrase completes it: woe IS for them. L6 · R2

لِّلَّذِينَword 2

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. The prefix لِّ 'to/for' is one of the common prepositions: woe 'TO those'. L4 · R2

Relative Pronoun · اسم موصولA relative pronoun is a word that hooks a whole describing sentence onto whom it stands for, and ٱلَّذِينَ — written لَّذِينَ after the لِّ — is the form for a group of people: 'those who'. It carries the sentence 'write the book with their own hands'. L5 · R13

Significance — from the tafsir

"Waylun (woe)" carries meanings of destruction and perishing, a well-known word in the Arabic language — here for another category among them who called to misguidance with falsehood and lies about Allah, thriving on unjustly amassing people's property.

Ibn Kathir (abridged), on 2:78–79

Grammar — lesson evidence

يَكْتُبُونَword 3

Verb · فعلA verb is a word for an action tied to a time. يَكْتُبُ names an action — writing — from the root كتب: to write, prescribe, decree. L1 · R7

Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. يَكْتُبُونَ opens with the letter يَ — the 'they' prefix — standing before the root letters: 'they write'. L8 · R3

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. يَكْتُبُونَ 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 يَكْتُبُونَ 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', the writers; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4

ٱلْكِتَـٰبَword 4

Definite Article · أل التعريفThe definite article is the prefix ال attached to the front of a naming word to mean 'the'. ٱلْكِتَٰبَ wears that prefix, and its ل keeps its own sound, written with the sukūn ـْ — the small circle meaning no vowel follows: al-kitāb, 'the book'. L2 · R9

Noun · اسمA word that accepts ال — the prefix meaning 'the' — is a noun, a naming word. كِتَٰبَ names the book, from the root كتب — to write, prescribe, decree; book, scripture. 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. كِتَٰبَ 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 ب of كِتَٰبَ. 'The book' is what their writing lands on — a book of their own making. L9 · R3

بِأَيْدِيهِمْword 5

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. The prefix بِ 'with' is one of the common prepositions: write 'WITH their hands'. L4 · R2

Noun · اسمA noun names a person, place, thing, or body part. أَيْدِي names hands, from the root يدي — a hand. L1 · R6

Feminine Noun · اسم مؤنثSome naming words are grammatically 'she' — feminine — without any visible marker and must be memorized, among them the paired parts of the body, like يَد 'hand'. أَيْدِي, hands, is the plural of exactly that word. L2 · R2

Plural Noun · جمعA plural noun refers to three or more, made either by adding an ending or by reshaping the word from the inside — a 'broken' plural. أَيْدِي is such a reshaped plural of يَد 'hand': 'hands'. L2 · R6

Genitive · مجرورThe genitive is the ending a naming word takes after a preposition, usually a kasrah ـِ — a small stroke below the last letter. أَيْدِي is pulled into that role by the بِ at its front, but it closes on a long ي, a shape that cannot carry the changing mark — so the genitive here is the role it fills, not a mark on show. L2 · R12

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word; attached to a naming word, it shows possession. The ending هِمْ on بِأَيْدِيهِمْ stands for 'their': THEIR OWN hands. 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 هِمْ fills that owner slot: 'the hands OF them'; a pronoun keeps one fixed written shape, so the genitive is the role it fills. L5 · R5

Significance — from the tafsir

Ibn 'Abbas said: Allah told you that the People of the Book altered the Book of Allah, changed it, and wrote another book with their own hands, then said, "This book is from Allah," so that they acquired a small profit by it.

ثُمَّword 6

Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. ثُمَّ is such a helper word. L1 · R8

Conjunction · حرف عطفA conjunction is a particle that joins words or sentences, and ثُمَّ means 'then' — the next thing after a gap. They write — THEN they make their claim about it. L4 · R4

يَقُولُونَword 7

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. يَقُولُونَ opens with the letter يَ — the 'they' prefix — standing before the root letters: 'they say'. L8 · R3

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. يَقُولُونَ is one of those five shapes, and its نَ is kept — the normal, untrimmed mood. L10 · R10

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. يَقُولُونَ shows that true middle letter و of the root قول in plain view. L24 · R4

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending ونَ on يَقُولُونَ 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', the speakers; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4

هَـٰذَاword 8

Demonstrative Pronoun · اسم إشارةA demonstrative pronoun is a pointing word that singles out a specific thing, and هَٰذَا is the near pointing word: 'this' — the very book their hands wrote. L3 · R8

Subject (Mubtada') · مبتدأThe subject is the word a sentence opens by talking about — its topic — standing in the nominative, the topic's form, usually shown by a ḍammah ـُ, a small curl above the last letter. Inside their claim, هَٰذَا 'this' is that topic, completed by 'from Allah'; a pointing word 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 whole claim 'this is from Allah' is what their saying lands on, and هَٰذَا anchors it; a pointing word keeps one fixed written shape, so the accusative is the role it fills, not a mark on show. L9 · R3

مِنْword 9

Particle · حرفA particle is a small helper word with no meaning standing alone; it takes no ending and does not name or act. مِنْ 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. مِنْ 'from' is one of the common prepositions: 'FROM the presence of Allah'. L4 · R2

عِندِword 10

Noun · اسمA word whose final vowel mark changes with its job in the sentence is a noun, a naming word — even a little place word like this one. عِندِ means 'the presence of, at', from the root عند — near, with. L1 · R5

Genitive · مجرورThe genitive is the ending a naming word takes after a preposition, shown by a kasrah ـِ — a small stroke below the last letter. عِندِ ends in exactly that kasrah ـِ, pulled into it by the preposition مِنْ before it. L2 · R12

ٱللَّهِword 11

Noun · اسمA noun names a person, place, thing, or idea — including proper names. ٱللَّهِ is the proper name of Allah. L1 · R6

Genitive · مجرورThe genitive is the ending a naming word takes as the owner in an 'of' phrase, shown by a kasrah ـِ — a small stroke below the last letter. ٱللَّهِ ends in exactly that kasrah ـِ as the second word of 'the presence OF Allah'. L2 · R12

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, the kasrah ـِ, a small stroke below the last letter. ٱللَّهِ fills that owner slot after عِندِ, wearing that very kasrah: 'the presence OF Allah' — the false claim of their book's source. L5 · R5

لِيَشْتَرُوا۟word 12

Preposition · حرف جرA preposition is a little word that relates one thing to another. The prefix لِ 'to/for' here carries the sense 'so that', tying the writing and the claim to their motive: to barter it away. L4 · R2

Verb · فعلA verb is a word for an action tied to a time. يَشْتَرُ names an action — bartering, exchanging — from the root شري: to buy, to purchase, to sell. L1 · R7

Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. After the لِ, the verb opens with the letter يَ — the 'they' prefix — standing before the rest: 'they barter'. L8 · R3

Subjunctive Mood · الفعل المنصوبThe subjunctive is the mood a present tense verb takes after particles like أَنْ, لَنْ, كَيْ, and the purpose لِـ; for the masculine plural shape the marker is the DROPPING of the final نَ. يَشْتَرُوا۟ stands right after that purpose لِ, and its plural ending has lost that نَ — the full shape would end ـُونَ — exactly the subjunctive's sign. L10 · R4

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. يَشْتَرُوا۟ belongs to those five shapes, and its نَ is dropped — the sign that a mood-changing word, here the purpose لِ, stands before it. L10 · R10

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, and that letter loves to slip away. يَشْتَرُوا۟ is the root شري — its final weak ي does not show here at all; the word closes straight onto the 'they' ending وا۟. L24 · R7

Form VIII Verb · اِفْتَعَلَA Form VIII verb tucks an extra ت inside, right after the first root letter, usually giving a do-it-for-oneself sense. لِيَشْتَرُوا۟ shows exactly that تَ after its first root letter ش: bartering to gain for themselves. L13 · R4

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of a verb. The ending وا۟ on لِيَشْتَرُوا۟ 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 وا۟ is that doer, 'they', the barterers; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4

بِهِۦword 13

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. The prefix بِ 'with' is one of the common prepositions: exchange 'with it' — trade it away. L4 · R2

Detached Pronoun · ضمير منفصلA pronoun is a mini-word standing in for a name, here هِۦ 'it' — the book their hands wrote. Though the label reads it as a standalone word, it is written joined after the preposition بِ and works like the glued-on endings for 'his/it': 'with it'. L3 · R7

ثَمَنًۭاword 14

Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـً — is a noun, a naming word. ثَمَنًا names a price, from the root ثمن — price. L1 · R2

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

Indefinite Noun · نكرةAn indefinite noun means 'a' or 'any' one — no particular one named — and is marked by tanwīn, the doubled end-vowel. ثَمَنًا ends in the doubled fathah ـً: 'a price'. L2 · R8

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 — doubled here to the tanwīn ـً. ثَمَنًا ends in exactly that doubled fathah ـً. 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 doubled fathah ـً at the end of ثَمَنًا. 'A price' is what their bartering aims to take in. L9 · R3

قَلِيلًۭا ۖword 15

Noun · اسمA word that accepts tanwīn — the doubled end-vowel mark ـً — is a noun, a naming word; Arabic counts describing words like this among its naming words. قَلِيلًا means 'little', from the root قلل: to be few, little, small in quantity. L1 · R2

Indefinite Noun · نكرةAn indefinite noun is general — not one named instance — and is marked by tanwīn, the doubled end-vowel. قَلِيلًا ends in the doubled fathah ـً, matching the 'a price' it describes. L2 · R8

Accusative · منصوبThe accusative is an ending shown by a fathah ـَ — a small slanted stroke above the last letter — doubled here to the tanwīn ـً. قَلِيلًا ends in exactly that doubled fathah ـً, copying the ending of ثَمَنًا, the word it describes. L2 · R11

Adjective · صفةAn adjective is a describing word that comes after its naming word — the opposite of English order. قَلِيلًا follows ثَمَنًا 'a price' and copies its ending: both carry the doubled fathah ـً, indefinite and accusative alike — 'a price — a LITTLE one'. L7 · R1

Significance — from the tafsir

Al-Hasan Al-Basri said: "The little amount here means this life and all that it contains."

Ibn Kathir (abridged), on 2:78–79

So far: So woe to those who write the "scripture" with their own hands, then say, "This is from Allāh," in order to exchange it for a small price.

Subject (Mubtada') · مبتدأThe subject is the naming word a sentence opens by talking about — its topic — standing in the nominative, shown here by the doubled ḍammah ـٌ on وَيْلٌ. 'Woe' is the topic, and 'to them' completes it: woe IS theirs. L6 · R2

لَّهُمword 17

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. The prefix لَّ 'to/for' is one of the common prepositions: woe 'TO them'. L4 · R2

Detached Pronoun · ضمير منفصلA pronoun is a mini-word standing in for a name, here هُم 'them'. 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 'their/them', naming those the woe is for: 'to them'. L3 · R7

مِّمَّاword 18

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. مِنْ 'from/of' is one of the common prepositions, written here as مِّ fused with the word after it: woe 'FOR what' their hands wrote. L4 · R2

Relative Pronoun · اسم موصولA relative pronoun is a word that hooks a whole describing sentence onto what it stands for, and مَا is the form for non-human things: 'that which'. The مَّا of مِّمَّا carries the sentence 'their hands have written'. L5 · R13

كَتَبَتْword 19

Verb · فعلA verb is a word for an action tied to a time. كَتَبَتْ names an action — writing — from the root كتب: to write, prescribe, decree. L1 · R7

Past Tense Verb · فعل ماضٍA past tense verb describes what already happened, and who did it is shown by an ending added to the verb. The ending تْ — the 'she' marker, capped with the sukūn ـْ, the small circle meaning its sound stops there — sits on كَتَبَتْ: 'it wrote', speaking of the hands as 'she'. L8 · R2

أَيْدِيهِمْword 20

Noun · اسمA noun names a person, place, thing, or body part. أَيْدِي names hands, from the root يدي — a hand. L1 · R6

Feminine Noun · اسم مؤنثSome naming words are grammatically 'she' — feminine — without any visible marker and must be memorized, among them the paired parts of the body, like يَد 'hand'. أَيْدِي, hands, is the plural of exactly that word — which is why the verb before it wears the 'she' ending تْ. L2 · R2

Plural Noun · جمعA plural noun refers to three or more, made either by adding an ending or by reshaping the word from the inside — a 'broken' plural. أَيْدِي is such a reshaped plural of يَد 'hand': 'hands'. L2 · R6

Nominative · مرفوعThe nominative is the ending a naming word takes as the subject of its sentence, usually a ḍammah ـُ — a small curl above the last letter. أَيْدِي closes on a long ي, a shape that cannot carry that changing mark — so the nominative here is the role it fills as the doer, not a mark on show. L2 · R10

Doer (Fa'il) · فاعلThe doer is the one performing the action in a verb-first sentence, standing in the nominative — the doer's form, usually a ḍammah ـُ, a small curl above the last letter. 'Their hands' are what did the writing; the word's fixed long ي ending shows no mark, so the nominative is the role it fills. L9 · R2

Attached Pronoun · ضمير متصلAn attached pronoun is a mini-word glued onto the end of another word; attached to a naming word, it shows possession. The ending هِمْ on أَيْدِيهِمْ stands for 'their': THEIR hands. 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 هِمْ fills that owner slot: 'the hands OF them'; a pronoun keeps one fixed written shape, so the genitive is the role it fills. L5 · R5

Significance — from the tafsir

"Woe to them for what their hands have written" — woe to them because of the lies, falsehood and alterations they wrote with their own hands; Ibn 'Abbas said the torment will be theirs because of those lies.

Conjunction · حرف عطفA conjunction is a particle that joins words or sentences, and the joined word takes the same ending as the one before the joining. The prefix وَ 'and' joins this second woe to the first — both وَيْلٌ carry the same doubled ḍammah ـٌ. L4 · R4

Present Tense Verb · فعل مضارعA present tense verb is identified by one of the four prefix letters remembered as أَنَيْتُ. يَكْسِبُونَ opens with the letter يَ — the 'they' prefix — standing before the root letters: 'they earn'. L8 · R3

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. يَكْسِبُونَ 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 يَكْسِبُونَ 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', the earners; a pronoun keeps one fixed shape, so no ḍammah appears — the nominative is the role it fills. L9 · R4

Significance — from the tafsir

"And woe to them for that they earn thereby" — woe to them because of the property they unjustly acquired from people, be they commoners or otherwise, as Ibn 'Abbas said.

Ibn Kathir (abridged), on 2:78–79

So far: So woe to those who write the "scripture" with their own hands, then say, "This is from Allāh," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn.
