The Basic Idea
A Murakkab Iḍāfī (possessive compound) is a compound in which one noun is related or attributed to another noun — the relationship of possession or connection (تَعَلُّق / نِسْبَت). In English this is expressed by “of” or the apostrophe-s: the book of Allah / Allah’s book.
The two parts
🟩 المُضَاف (Muḍāf) — the noun that is being attributed; the possessed thing. In كِتَابُ اللهِ, the word كِتَابُ (book) is the muḍāf.
🟨 المُضَاف إِلَيْه (Muḍāf Ilayh) — the noun towards which the attribution is made; the possessor. In the same example, اللهِ is the muḍāf ilayh.
the Book of Allah · the Messenger of Allah
Word order — Arabic vs. Urdu/English possessive
In Arabic the muḍāf comes first and the muḍāf ilayh comes after it: كِتَابُ اللهِ. In Urdu (اللہ کی کتاب) and in the English apostrophe form (Allah’s book) the possessor comes first — so when translating, start from the second noun, then translate the first: “the book of Allah.”
Rules of Construction · القواعد
Five rules govern how a possessive compound is built.
-
The muḍāf never takes ال before it, nor tanwīn after it.
Saying اَلْكِتَابُ اللهِ or كِتَابٌ اللهِ is wrong. The correct form is كِتَابُ اللهِ.
-
Since tanwīn cannot appear on the muḍāf, the ن of the dual and the sound plural also drops.
“The two doors of the mosque” is بَابَا الْمَسْجِدِ, not بَابَانِ الْمَسْجِدِ. “The Muslims of the village” is مُسْلِمُو الْقَرْيَةِ, not مُسْلِمُونَ الْقَرْيَةِ.
-
The muḍāf ilayh is always in the genitive state (حالتِ جرّ — majrūr).
Its last letter carries a kasrah (or the genitive form of its ending): كِتَابُ اللهِ · رَبُّ الْعَالَمِينَ
-
In translation the compound generally gives the sense of “of” (Urdu: کا / کے / کی).
كِتَابُ اللهِ = the book of Allah (اللہ کی کتاب) · رَسُولُ اللهِ = the messenger of Allah (اللہ کا رسول).
-
One word may be muḍāf and muḍāf ilayh at the same time — a chained (cascaded) iḍāfah.
Both sets of rules apply to that middle word: no ال, no tanwīn (as muḍāf) and a genitive ending (as muḍāf ilayh). Example: بِنْتُ رَسُولِ اللهِ — see Tab III.
Examples from the Qur’an
Each compound below is colour-coded: muḍāf in teal, muḍāf ilayh in gold. Notice the muḍāf never has ال or tanwīn, and the muḍāf ilayh always ends majrūr. Translate from the second word backwards.

| بَيْنَ الْبَحْرَيْنِ | An-Naml 27:61 | between | the two seas | between the two seas بَيْنَ is always a muḍāf (لازم الإضافة); here it is manṣūb as a ẓarf |
| جَزَآءُ الْكَافِرِينَ | At-Tawbah 9:26 | recompense | the disbelievers | the recompense of the disbelievers |
| أَصْحَابُ الْجَنَّةِ | Al-Ḥashr 59:20 | companions | the garden | the companions of Paradise |

| أَبْوَابُ السَّمَاءِ | Al-Aʿrāf 7:40 | doors | the sky | the gates of the sky |
| صَاحِبَا السِّجْنِ | Yūsuf 12:39 | two companions | the prison | the two companions of the prison note: صاحبانِ → صاحبَا (rule 2 — the ن drops) |
Watch the endings
In every row: the muḍāf carries a single ḍammah (never tanwīn, never ال), while the muḍāf ilayh is majrūr — kasrah on singulars (اللهِ), ـَيْنِ on duals (الْبَحْرَيْنِ), and ـِينَ on sound masculine plurals (الْكَافِرِينَ).
Cascaded Iḍāfah — the Chain
When three (or more) nouns are chained, every middle word plays a double role: it is the muḍāf ilayh of the word before it and the muḍāf of the word after it. Both rules apply to it at once: it loses ال and tanwīn, and it stands in the genitive.
بِنْتُ رَسُولِ اللهِ
“the daughter of the Messenger of Allah”
Check the rules on رَسُولِ: (i) no ال at its start — muḍāf rule applied; (ii) kasrah at its end — muḍāf ilayh rule applied.
بَيْتُ وَزِيرِ الْمَلِكِ
“the house of the minister of the king”
Qur’anic chains
“the traces of the mercy of Allah” — رَحْمَةِ is muḍāf ilayh of آثَارُ and muḍāf of اللهِ.
“before the Day of Reckoning” — يَوْمِ carries both roles.
“the two hands of Abū Lahab” — note يَدَانِ → يَدَا (the ن drops, rule 2), and أَبِي shows its genitive form with ي.

Advanced Rules of the Muḍāf
Beyond the five basic rules, the possessive structure interacts with other grammar: description (نعت / منعوت), the vocative (المنادى), the iʿrāb of the muḍāf, and the special noun ذُو and its sisters.
1 · The muḍāf as نعت and the muḍāf ilayh as منعوت
In a possessive structure, the مُضَاف can act as the نَعْت (describer), and the مُضَاف إِلَيْه as the مَنْعُوت (described).
The tarkīb of this is written as follows:
2 · The muḍāf in the vocative — اَلْمُنَادَى
The اَلْمُنَادَى (the one being called) can come in two forms:
1. In a possessive phrase — the مُضَاف will be مَنْصُوْبٌ (accusative):
2. Outside a possessive phrase — it takes one ضَمَّةٌ:
3 · Dropping the ي from the مُنَادَى
If the munādā is muḍāf to the possessive pronoun ي (“my”), the ي may be dropped. The مُضَاف keeps its كَسْرَةٌ:
“O my people!” · “O my Lord!” — the kasrah at the end still points to the dropped ي.
4 · A possessive phrase can be any part of the sentence
The compound as a whole can occur as fāʿil, mafʿūl, or any other main part of a sentence. The مُضَاف does not have its own iʿrāb — its iʿrāb depends on where the compound occurs in the sentence. (Only the muḍāf ilayh is fixed: always majrūr.)
The tarkīb of this is written as follows:
Here يَوْمَ is manṣūb because the compound is a مفعول فيه (adverb of time) — not because it is muḍāf.
5 · The dual (الْمُثَنَّى) and sound masculine plural (جَمْعُ الْمُذَكَّرِ السَّالِمُ) as muḍāf
The ن at the end of the dual and the sound masculine plural is semi-equivalent to a تَنْوِيْنٌ. Therefore, when they occur as a مُضَاف, their ن drops — just as tanwīn drops from a singular muḍāf.
Muhammad’s two sisters
the teachers of the children
6 · ذُوْ and its sisters
ذُوْ (“possessor of”) and its sisters are used as مُضَاف, and their مُضَاف إِلَيْه is always a noun with a general meaning. They are translated as a possessive phrase or an adjective phrase:
The dual, plural, and feminine forms of ذُوْ:
| Singular | Dual | Plural | |
|---|---|---|---|
| Masculine | ذُوْ | ذَوَا | ذَوُوْ / أُولُوْ |
| Feminine | ذَاتُ | ذَوَاتَا | ذَوَاتُ / أُولَاتُ |
7 · ذُوْ as a نَعْت
After a نَكِرَةٌ (indefinite) word, ذُوْ together with its muḍāf ilayh becomes the نَعْت (adjective) of that word.
The tarkīb of جَاءَ رَجُلٌ ذُوْ عِلْمٍ is written as follows:
The pair ذُوْ عِلْمٍ is internally an iḍāfah, and externally serves as one naʿt describing رَجُلٌ.
