نَحْوُ قَوْلِهِ تَعَالَى: «هَذَا يَوْمَ يَنْفَعُ الصَّادِقِينَ صِدْقُهُمْ».
Translation: As in the cited Qurʾānic expression: “This is the day when the truthful benefit from their truthfulness.”
Yawm introduces a time expression followed by a verbal clause. The book cites the phrase under the discussion of adverbs linked to clauses and possible building.
Book example: يَنْفَعُ الصَّادِقِينَ صِدْقُهُمْ.
Their truthfulness benefits the truthful.
Yanfaʿu: verb; al-ṣādiqīna: object, accusative by yāʾ; ṣidqu: nominative subject and muḍāf; -hum: genitive complement.
Reading and syntax distinction: Both nominative yawmu and accusative yawma readings are transmitted here. With yawmu it can be the predicate of hādhā; the accusative has adverbial and other classical grammatical analyses. The source cites the passage in its discussion of building, not as evidence for one exclusive reading.
