وَلَوْ جَعَلْنَاهُ مَلَكًا لَّجَعَلْنَاهُ رَجُلًا وَلَلَبَسْنَا عَلَيْهِم مَّا يَلْبِسُونَ
Had We made him an angel, We would have surely made him a man, and We would have surely confounded them just as they confound [the truth now].
Agha Ali Puya Commentary
Commentary on Quran 6:9
[Pooya/Ali Commentary 6:9] Even if an angel was sent to act as a prophet, he would also appear to them, in form and appearance, like a man; in which case their already confused notions about spiritual life would be still more confounded.
