Rules and Spelling Principles of the Iḍāfah

1. Introduction to the Iḍāfah and Its Features

● In this section, we will study the third and most frequently used kind of incomplete phrase: the iḍāfah / possessive construction.
● We will learn that a construction showing possession or a relationship between two nouns is called an iḍāfah, such as 'the Messenger of Allah.'
● We will understand the grammatical definitions of the first term (muḍāf) and the second term (muḍāf ilayh).
● We will study in detail the two important spelling rules that apply to the first term.

2. Meaning of the First and Second Terms of the Iḍāfah

● An iḍāfah has two basic parts:
1. First term (muḍāf): The noun related to the second noun, such as 'book.'
2. Second term (muḍāf ilayh): The noun to which the first noun is related, such as 'Zayd.'
● Difference in order: In English, we may say 'Zayd's book,' placing Zayd first. In Arabic, the order is the reverse: the first term comes first, followed by the second term.
○ Arabic order = muḍāf + muḍāf ilayh
○ For example: كِتَابُ زَيْدٍ (Zayd's book)

3. The Two Basic Spelling Rules for the Muḍāf

● The following two rules apply to a noun when it becomes the muḍāf:
1. The muḍāf does not take al-: Al- can never be added at the beginning of the muḍāf.
2. The muḍāf has a light ending: Tanwīn is always removed from its final letter, leaving only one ḍammah, fatḥah, or kasrah.
● Study this chart showing the light endings of singular nouns and sound feminine plurals:

NominativeAccusativeGenitiveType
كِتَابُ (original: كِتَابٌ)كِتَابَ (original: كِتَابًا)كِتَابِ (original: كِتَابٍ)Masculine singular
جَنَّةُ (original: جَنَّةٌ)جَنَّةَ (original: جَنَّةً)جَنَّةِ (original: جَنَّةٍ)Feminine with tāʾ marbūṭah
آيَاتُ (original: آيَاتٌ)آيَاتِ (original: آيَاتٍ)آيَاتِ (original: آيَاتٍ)Sound feminine plural
أَبْوَابُ (original: أَبْوَابٌ)أَبْوَابَ (original: أَبْوَابًا)أَبْوَابِ (original: أَبْوَابٍ)Broken plural

4. The Rule of Dropping the Final Nūn from Dual and Plural Forms

● If the noun used as a muḍāf is dual or sound masculine plural, its final nūn must be dropped to lighten its ending:

NominativeAccusative and genitiveType
كِتَابَا (original: كِتَابَانِ)كِتَابَيْ (original: كِتَابَيْنِ)Masculine dual
يَدَا (original: يَدَانِ)يَدَيْ (original: يَدَيْنِ)Feminine dual
بَنُو (original: بَنُونَ)بَنِي (original: بَنِينَ)Sound masculine plural

● For example, 'the boy's two hands' -> يَدَا الْوَلَدِ; the nūn of يَدَانِ is dropped.

5. The Case Rule for the Muḍāf Ilayh

● After the two basic rules for the muḍāf, the muḍāf ilayh has one rule:
○ The muḍāf ilayh is always genitive (majrūr).
● Deciding definiteness and indefiniteness:
○ The muḍāf is not independently definite or indefinite; its status follows the muḍāf ilayh.
○ If the muḍāf ilayh is definite, the muḍāf is automatically treated as definite.
○ English uses words such as 'a,' 'any,' or 'some' to express an indefinite meaning, as in 'a traveller on a path' -> عَابِرُ سَبِيلٍ, where سَبِيلٍ is an indefinite muḍāf ilayh.
