1 · What أَداة means
Look at the word itself first. أَداة (adāh) = a tool / instrument; its plural is أَدَوات (adawāt). So أَدَواتُ الاسْتِفْهام (adawātu-l-istifhām) = "the tools of questioning" — the words with which a question is built. اِسْتِفْهام (istifhām) translates as "questioning / asking."
2 · Two classes of interrogative — حُرُوف and أَسْماء
You know the three classes of word in Arabic: اِسْم (ism, noun), فِعْل (fiʿl, verb) and حَرْف (ḥarf, particle). The interrogatives split across two of those:
| Class | Which words | Count |
|---|---|---|
| حُرُوفُ الاسْتِفْهام — interrogative particles | هَلْ and the هَمْزة (the أ) | 2 |
| أَسْماءُ الاسْتِفْهام — interrogative nouns | أَيّ · كَمْ · أَيْنَ · مَتَى · كَيْفَ · مَنْ · ما · ماذا · لِماذا | 9 |
Take the two groups together and you call the whole set أَدَواتُ الاسْتِفْهام — eleven words. In the textbook they are printed in red so you can see them at a glance; read them straight through.
3 · The rule that covers all eleven: the interrogative comes FIRST
Run your eye down every example in the unit along one line and you will see it: the question word begins the sentence. It never comes in the middle, and never at the end. In Tamil we ask the other way round — "this name what?" — with the question word landing last. Arabic does not do that. To ask "who is this?" you must say مَنْ هذا؟ (man hādhā?), never hādhā man?
4 · The eleven, one at a time
| # | Particle | Asks about | Example | Answer / meaning |
|---|---|---|---|---|
| 1 | هَلْ | yes / no (affirmative sentences only) | هَلْ أَكَلْتَ؟ | did you eat? |
| 2 | الهَمْزة (أ) | yes / no (affirmative and negative) | أَلَمْ تَأْكُلْ؟ | did you not eat? |
| 3 | أَيّ | which one of several | أَيَّ كِتابٍ تُرِيدُ؟ | كِتابَ القَواعِدِ (the grammar book) |
| 4 | كَمْ | how many / what time / how much | كَمْ طِفْلاً؟ | خَمْسَةُ أَطْفالٍ (five children) |
| 5 | أَيْنَ | place | أَيْنَ الكِتابُ؟ | الكِتابُ فِي المَكْتَبَةِ (in the library) |
| 6 | مَتَى | time | مَتَى تُسافِرُ؟ | أُسافِرُ غَداً (I travel tomorrow) |
| 7 | كَيْفَ | state / manner | كَيْفَ حالُكَ؟ | how are you? (lit. how is your condition) |
| 8 | مَنْ | a person (rational) | مَنْ هذا؟ | هذا أَحْمَدُ (this is Aḥmad) |
| 9 | ما | a non-person, before a noun | ما هذا؟ | هذا كِتابٌ (this is a book) |
| 10 | ماذا | a non-person, before a verb | ماذا حَصَلَ؟ | what happened? |
| 11 | لِماذا | a reason | لِماذا ذَهَبْتَ؟ | why did you go? |
1 · هَلْ — the yes/no particle
To ask "is it so, or not?" there are exactly two words: هَلْ and the هَمْزة. Both stand at the start of the sentence and both may come before a verb or before a noun, with the same meaning:
2 · الهَمْزة — the same question, and the only one allowed with a negative
The هَمْزة (the أ prefixed to the sentence) does everything هَلْ does:
Here is the whole difference between the two. هَلْ comes only with an affirmative sentence. The hamzah comes with affirmative and negative alike. So you cannot say hal lam taʾkul — لَمْ is a negative, and هَلْ is barred from it. With a negative, only the hamzah:
You recite that very pattern in the Qur'an:
3 · أَيّ — "which one?", and it is always a مُضاف
When many things are in front of you and you must single one out, that is أَيّ — English "which." Unlike هَلْ and the hamzah it carries a rule of its own: أَيّ is always a مُضاف (muḍāf), and the noun after it is its مُضافٌ إِلَيْهِ (muḍāf ilayh) — so that noun is always majrūr (kasrah): أَيُّ كِتابٍ, أَيُّ طَعامٍ. The iʿrāb therefore shows on أَيّ itself, which appears in three shapes according to its own role in the sentence:
| Role of أَيّ | Ending | Example | Meaning |
|---|---|---|---|
| مَفْعُول بِهِ (object) | fatḥah — أَيَّ | أَيَّ كِتابٍ تُرِيدُ؟ | Which book do you want? |
| مَفْعُول بِهِ (object) | fatḥah — أَيَّ | أَيَّ طَعامٍ أَكَلْتَ؟ | Which food did you eat? |
| فاعِل (subject) | ḍammah — أَيُّ | أَيُّ رَجُلٍ جاءَ؟ | Which man came? |
| after a حَرْف جَرّ | kasrah — أَيِّ | فِي أَيِّ مَسْجِدٍ تُصَلِّي؟ | In which mosque do you pray? |
- أَيَّ كِتابٍ تُرِيدُ؟ — ayya kitābin turīd? — answered كِتابَ القَواعِدِ (kitāba-l-qawāʿid, "the grammar book").
- In أَيُّ رَجُلٍ جاءَ؟ the verb is جاءَ and أَيُّ رَجُلٍ is the fāʿil, so ayy is marfūʿ.
- A student's objection, and the answer: "shouldn't it be rajulun, not rajulin?" — No. It is رَجُلٍ, because it is the مُضافٌ إِلَيْهِ of ayy, and a مُضافٌ إِلَيْهِ always carries kasrah — that never changes. Likewise أَيَّ طَعامٍ and أَيِّ بَيْتٍ.
4 · كَمْ — asking a number, in three shapes
كَمْ (kam) asks "how many?" What follows it is not a muḍāf ilayh construction like ayy's: after kam comes a singular noun in naṣb (fatḥah tanwīn — it is the tamyīz, the specifier), never a plural.
In Tamil we ask with a plural ("how many children"); Arabic keeps the noun singular: كَمْ قَلَماً، كَمْ كِتاباً، كَمْ رَجُلاً، كَمْ بَيْتاً، كَمْ مَسْجِداً — and you must never say kam aqlāman.
The one exception — clock time. There is exactly one place where the word after kam takes الـ, and that is asking the time:
Say كَمْ ساعَةً (kam sāʿatan) on the pattern of kam ṭiflan and you have asked something else — "how many hours." And you cannot ask the time with ما السّاعةُ؟ — ask it that way and people will laugh at you.
The third shape — price, kam joined to the preposition بِـ:
So kam works three ways: (1) كَمْ طِفْلاً — how many; (2) كَمِ السّاعَةُ — what time; (3) بِكَمْ — how much.
5 · أَيْنَ — asking about a place
أَيْنَ (ayna) asks where, and the answer must carry the preposition فِي naming the place:
Unlike kam, which had three shapes including one joined to بِـ, أَيْنَ comes only as أَيْنَ — no particle ever attaches to it. Also: أَيْنَ تَسْكُنُ؟ (ayna taskun?) — "Where do you live?"
6 · مَتَى — asking about time
مَتَى (matā) asks when. Like ayna it takes no attached preposition, and it may come before a verb or before a noun:
7 · كَيْفَ — asking about state or manner
كَيْفَ (kayfa) = "how." No preposition joins it either, and a noun or a verb may follow:
Past or present, it works for all. So أَيْنَ، مَتَى، كَيْفَ are three of a kind — place, time, manner — and after all three either a noun or a verb may come.
8 · مَنْ — for persons only
مَنْ (man) asks about the rational / human (ʿāqil). English draws no such distinction; Arabic does. مَنْ is for persons only:
(هذا is an اِسْمُ إِشارة — a demonstrative — and does not change form here.)
9 · ما — for non-persons, before a NOUN
ما (mā) covers everything that is not a person, and it comes only before a noun:
10 · ماذا — for non-persons, before a VERB
This is the split to fix in memory. Put ما in front of a verb and it stops being a question at all — it becomes a negation: ما فَعَلْتَ = "you did not do," ما حَصَلَ = "it did not happen." So to ask a question before a verb you must add the extra ذا:
ما and ماذا carry the same meaning; the rule is only about what follows — ما before a noun, ماذا before a verb.
11 · لِماذا — asking a reason
لِـ (li-) is a حَرْف جَرّ meaning "for," and it marks a reason. Join it to ماذا and you get لِماذا — "for what? / why?" It may come before a verb or before a noun:
With that, all eleven أَدَواتُ الاسْتِفْهام have been covered, and the construction each one takes.
5 · Exercise 1 — eleven sentences, choose the right interrogative
The exercise prints the أدوات above and then gives eleven sentences, each with the interrogative blanked out. The items the Sheikh worked through:
| Sentence | Why that word |
|---|---|
| لِماذا غِبْتَ؟ | the verb is already 2nd person ("you were absent"), so what is missing is the reason |
| مَنْ سافَرَ مَعَكَ؟ | the answer wanted is a person |
| كَيْفَ الحالُ؟ | asking about a state |
| ماذا تُرِيدُ؟ | a verb follows, so ما will not do — it must be ماذا |
| أَيَّ بَيْتٍ تُرِيدُ؟ | one house singled out of several; the muḍāf ilayh takes kasrah |
| أَتُسافِرُ إِلى مَكَّةَ؟ | a plain yes/no question |
| كَيْفَ تُسافِرُ إِلى مَكَّةَ؟ | asking the manner of travel |
| مَتَى تُسافِرُ؟ | asking the time of travel |
| هَلْ هذا كِتابُكَ؟ | yes/no, and the sentence is affirmative, so هَلْ is allowed |
| كَمْ رِيالاً مَعَكَ؟ | the fatḥah tanwīn on رِيالاً appears only after كَمْ — that alone gives it away |
| أَيْنَ تُصَلِّي الجُمُعَةَ؟ | asking the place |
| أَجاءَ هارُونُ؟ | yes/no with the hamzah |
Two teaching points that came out of these items:
غابَ — the verb behind غِبْتَ
- غابَ (ghāba) = "he was hidden / he was absent." From the same root comes الغَيْب (al-ghayb, the unseen) — الإِيمانُ بِالغَيْبِ is believing in what is hidden from the senses. Used of absence: غابَ عَنِ الدَّرْسِ = "he was absent from the lesson"; غِبْتَ = "you were absent."
- For that first item you could of course build مَنْ غابَ؟ ("who was absent?") as a sentence in its own right — but with غِبْتَ in the blank's sentence, only لِماذا fits.
مَعَكَ vs عِنْدَكَ — a fine distinction
- كَمْ رِيالاً مَعَكَ؟ asks how much you have on you right now — in your hand, in your pocket.
- كَمْ رِيالاً عِنْدَكَ؟ asks what you possess — wallet level versus bank level, so to speak.
- Likewise كَمْ بَيْتاً عِنْدَكَ؟ ("how many houses do you own?") and كَمْ قَلَماً مَعَكَ؟ ("how many pens have you got with you?").
- On the travel item, both كَيْفَ and مَتَى would fit the sentence.
6 · Exercise 2 — ماذا vs مَا الَّذِي
A simple exercise on the أسماء. Two ways of asking the very same thing:
Both carry the same meaning. Note which interrogative each takes: with الَّذِي it is ما, not ماذا — because a noun follows, namely the relative الذي. That is §4's rule doing its work.
الَّذِي (alladhī) = "that which / the one which" — an اِسْم مَوْصُول (ism mawṣūl, relative noun). It is the same الذي as in the oath of the ḥadīth:
7 · Exercise 3 — the athar of ʿAbdullāh ibn az-Zubayr
Here you must frame a question and identify the parts. The passage: when the children saw ʿUmar [ibn al-Khaṭṭāb raḍiyallāhu ʿanhu] they all fled — except ʿAbdullāh ibn az-Zubayr. So ʿUmar asked him:
What the task asks you to find in it:
- a فِعْل (verb) with its فاعِل — specifically a verb whose fāʿil is a ضَمِير مُسْتَتِر (ḍamīr mustatir, a concealed pronoun);
- the جُمْلة اسْتِفْهامِيّة (jumlah istifhāmiyyah, the interrogative sentence) in the passage — which is لِماذا لَمْ تَفِرَّ مَعَ أَصْحابِكَ؟
Two more question-frames to build:
The eleven — WHAT EACH ASKS, AND WHAT FOLLOWS IT
| # | Particle | Asks | Class | What follows / rule | Example |
|---|---|---|---|---|---|
| 1 | هَلْ | yes / no | ḥarf | noun or verb — affirmative sentences only | هَلْ أَكَلْتَ؟ |
| 2 | الهَمْزة (أ) | yes / no | ḥarf | noun or verb — affirmative and negative | أَلَمْ تَأْكُلْ؟ |
| 3 | أَيّ | which one | ism | always مُضاف; next noun majrūr | أَيَّ كِتابٍ تُرِيدُ؟ |
| 4 | كَمْ | how many | ism | singular noun in naṣb (fatḥah tanwīn) | كَمْ طِفْلاً؟ |
| 5 | أَيْنَ | place | ism | noun or verb; answer needs فِي | أَيْنَ الكِتابُ؟ |
| 6 | مَتَى | time | ism | noun or verb; no attached particle | مَتَى تُسافِرُ؟ |
| 7 | كَيْفَ | state / manner | ism | noun or verb; no attached particle | كَيْفَ حالُكَ؟ |
| 8 | مَنْ | a person (ʿāqil) | ism | persons only | مَنْ هذا؟ |
| 9 | ما | a non-person | ism | only before a noun | ما اسْمُكَ؟ |
| 10 | ماذا | a non-person | ism | only before a verb | ماذا حَصَلَ؟ |
| 11 | لِماذا | a reason | ism | noun or verb (لِـ = "for") | لِماذا ذَهَبْتَ؟ |
- أَداة = tool · plural أَدَوات · اِسْتِفْهام = questioning.
- Split: حُرُوف = هَلْ + الهَمْزة (2); أَسْماء = the other 9.
- The interrogative is never in the middle or at the end — مَنْ هذا؟ and never hādhā man.
Traps that decide the answer
| Trap | Must recall |
|---|---|
| negative sentence | only the hamzah — أَلَمْ تَأْكُلْ؟ · never hal lam taʾkul |
| Qur'anic proof of that | أَلَمْ تَرَ كَيْفَ فَعَلَ رَبُّكَ (al-Fīl 105:1) |
| ما before a verb | it is a negation, not a question — ما فَعَلْتَ = "you did not do" |
| so a question before a verb | add ذا — ماذا حَصَلَ؟ · ماذا تُرِيدُ؟ |
| ما with الَّذِي | مَا الَّذِي بِيَدِكَ؟ = ماذا بِيَدِكَ؟ — ما, because a noun (الذي) follows |
| a fatḥah tanwīn on the noun | that ending only comes after كَمْ — كَمْ رِيالاً مَعَكَ؟ |
| never pluralise after كَمْ | كَمْ قَلَماً — never kam aqlāman |
| person vs thing | مَنْ هذا؟ (person) · ما هذا؟ (thing) |
أَيّ — three shapes, one rule
| Role | Ending | Example |
|---|---|---|
| مَفْعُول بِهِ (object) | أَيَّ (fatḥah) | أَيَّ كِتابٍ تُرِيدُ؟ · أَيَّ طَعامٍ أَكَلْتَ؟ |
| فاعِل (subject) | أَيُّ (ḍammah) | أَيُّ رَجُلٍ جاءَ؟ |
| after a حَرْف جَرّ | أَيِّ (kasrah) | فِي أَيِّ مَسْجِدٍ تُصَلِّي؟ |
- The word after أَيّ is its مُضافٌ إِلَيْهِ, so it is always majrūr: رَجُلٍ, طَعامٍ, بَيْتٍ.
- Answer to أَيَّ كِتابٍ تُرِيدُ؟ — كِتابَ القَواعِدِ.
كَمْ — three uses
| Use | Form | Example |
|---|---|---|
| how many | كَمْ + singular manṣūb | كَمْ طِفْلاً؟ — answer خَمْسَةُ أَطْفالٍ |
| what time (the one الـ exception) | كَمِ السّاعَةُ؟ | not ما السّاعةُ؟ · كَمْ ساعَةً = "how many hours" |
| how much (price) | بِكَمْ | بِكَمِ القَلَمُ؟ — answer القَلَمُ بِعِشْرِينَ رِيالاً |
Question → answer pairs to have by heart
| Question | Answer |
|---|---|
| أَيْنَ الكِتابُ؟ | الكِتابُ فِي المَكْتَبَةِ |
| أَيْنَ الرَّجُلُ؟ | الرَّجُلُ فِي البَيْتِ |
| أَيْنَ الحِمارُ؟ | الحِمارُ فِي المَزْرَعَةِ |
| مَتَى تُسافِرُ؟ | أُسافِرُ غَداً |
| مَتَى تَنامُ؟ | أَنامُ بَعْدَ قَلِيلٍ |
| مَنْ هذا؟ | هذا أَحْمَدُ |
| ما هذا؟ | هذا كِتابٌ |
