«إِنَّ الثَّمَانِينَ وَبُلِّغْتَهَا قَدْ أَحْوَجَتْ سَمْعِي إِلَى تَرْجُمَانٍ»
Indeed, reaching eighty—may you reach it—has made my hearing need an interpreter.
The host predication is «إِنَّ الثَّمَانِينَ ... قَدْ أَحْوَجَتْ». The intervening «وَبُلِّغْتَهَا» is a prayer addressed to the listener, not an object or circumstance of the main report. It is a parenthetical clause adding a relevant rhetorical point.
Recognizing iʿtirāḍ requires attention both to the clause's lack of a syntactic position in the host construction and to the continuing coherence of that construction.
