إِنَّ الْمَشْرُوعَ ـ وَهُوَ فِي بَدَايَتِهِ ـ يَحْتَاجُ إِلَى مُرَاقَبَةٍ.
The project—still at its beginning—requires monitoring.
Wa-huwa fī bidāyatihi is inserted between the main parts of the assertion in a parenthetic explanatory role. The core predication, inna al-mashrūʿa yaḥtāju ilā murāqaba, remains complete without it. The insertion supplies relevant background on why monitoring is fitting.
The classification as iʿtirāḍ is contextual: not every clause beginning wa-huwa must be parenthetical. Distinguish an insertion interrupting the main utterance from a circumstantial clause depicting an event's state.
