Surah Al-An'am, ayah 9

6:9

وَلَوۡ جَعَلۡنَٰهُ مَلَكٗا لَّجَعَلۡنَٰهُ رَجُلٗا وَلَلَبَسۡنَا عَلَيۡهِم مَّا يَلۡبِسُونَ ٩

Walaw ja'alnāhu malakal laja'alnāhu rajulan walalabasnā 'alayhim mā yalbisūn

And if We had made him [i.e., the messenger] an angel, We would have made him [appear as] a man, and We would have covered them with that in which they cover themselves [i.e., confusion and doubt].
