Itirad al-Shart ala al-Shart

I'tirad al-Shart 'ala al-Shart (The Interposition of a Condition upon a Condition) is a grammatical treatise by the grammarian Ibn Hisham al-Nahwi (708–761 AH / 1309–1360 CE) that examines the syntactic rules and interpretive consequences of stacking multiple conditional clauses before a single apodosis (jawab) Itirad al-Shart ala al-Sh…+1.

Subject and Scope

The treatise addresses sentences where two or more conditional particles occur in sequence before a single uttered apodosis, clarifying that although grammarians term the issue "the interposition of a condition upon a condition," the principle extends beyond two conditions to three or more Itirad al-Shart ala al-Sh…. Ibn Hisham authored the work to correct common confusions and misclassifications made by various grammarians and Quranic exegetes regarding what genuinely constitutes this syntactic pattern Itirad al-Shart ala al-Sh….

Excluded Constructions

Ibn Hisham systematically delineates five sentence structures that scholars frequently mislabel as instances of interposed conditions:

1. When the first condition is immediately followed by its own explicit apodosis, and the second condition appears only afterward, as in the verse: يَا قَوْمِ إِن كُنتُمْ آمَنتُم بِاللَّهِ فَعَلَيْهِ تَوَكَّلُوا إِن كُنتُم مُّسْلِمِينَ ("O my people, if you have believed in Allah, then rely upon Him, if you are Muslims" [Yunus: 84]) Itirad al-Shart ala al-Sh….
2. When the second condition is explicitly prefixed by the connective fa' of the apodosis (e.g., in takallama Zaydun fa-in ajada fa-ahsin ilayh), in which case the entire second conditional sentence serves as the apodosis of the first Itirad al-Shart ala al-Sh….
3. When the fa' is implied after particles such as amma, as in the verse: فَأَمَّا إِنْ كَانَ مِنَ الْمُقَرَّبِينَ فَرَوْحٌ وَرَيْحَانٌ [al-Waqi'ah: 88–89] Itirad al-Shart ala al-Sh….
4. When a subsequent conditional clause is conjoined to the first condition's verb with a coordinating conjunction, as in Surah Muhammad [47: 36–37], which Ibn Malik had erroneously classified under this category Itirad al-Shart ala al-Sh….
5. When the apodosis of both conditions is omitted because an earlier independent clause already indicates their meaning, as in Surah Hud [11: 34] ( وَلَا يَنفَعُكُمْ نُصْحِي إِنْ أَرَدتُ أَنْ أَنصَحَ لَكُمْ إِن كَانَ اللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ ) and Surah al-Ahzab [33: 50], contrary to Ibn Malik's parsing Itirad al-Shart ala al-Sh….

Syntactic and Legal Analysis

A genuine instance of interposed conditions is exemplified by conditional oaths or legal formulations such as in rakibti in labisti fa-anti taliq ("If you ride, if you dress, you are divorced") Itirad al-Shart ala al-Sh…. Ibn Hisham notes that while Ibn al-Dahhan reported that some grammarians disallowed this construction entirely, the majority of scholars permit it Itirad al-Shart ala al-Sh…. He substantiates its validity through Quranic evidence, such as the conjunction of lawla and law sharing a single apodosis in Surah al-Fath [48: 25] ( وَلَوْلَا رِجَالٌ مُّؤْمِنُونَ... لَعَذَّبْنَا ), al-Akhfash's parsing of Surah al-Baqarah [2: 180], and classical Arabic poetic evidence from the Hamasah collection and Ibn Durayd's Maqsurah Itirad al-Shart ala al-Sh…+1.

Regarding how the consequence takes effect, Ibn Hisham outlines the main viewpoints among scholars who allow the construction:

• The Majority of Grammarians and Jurists: The expressed apodosis belongs to the first condition, while the second condition has an elided apodosis indicated by the first clause and its answer Itirad al-Shart ala al-Sh…. As a result, the fulfillment of the conditioned outcome requires that the action of the second condition take place chronologically before the action of the first condition (e.g., the woman must first dress and then ride for the divorce to take effect) Itirad al-Shart ala al-Sh…+1.
• Ibn Malik's View: The expressed apodosis belongs to the first condition, but the second condition has no apodosis (neither uttered nor implied), functioning instead as a circumstantial qualifier (hal) restricting the first condition (i.e., "if you ride while dressed") Itirad al-Shart ala al-Sh….

Ibn Hisham rejects Ibn Malik's interpretation, arguing that positing a conditional particle without an apodosis violates established grammatical analogy, fails when two actions cannot be performed simultaneously (such as standing and sitting, or performing ablution and praying), and conflicts with the requirement that circumstantial clauses cannot denote future prospective events unless understood as anticipated states (hal muqaddarah) Itirad al-Shart ala al-Sh…+1.
