﴿ وَلَوْ جَعَلْنَٰهُ مَلَكًۭا لَّجَعَلْنَٰهُ رَجُلًۭا وَلَلَبَسْنَا عَلَيْهِم مَّا يَلْبِسُونَ ﴾

“And (even] if We had appointed an angel as Our message-bearer, We would certainly have made him [appear as] a man - and thus We would only have confused them in the same way as they are now confusing themselves.”

And had We appointed him the one who is sent down to them an angel We would assuredly have made him the angel a man that is We would have sent him in the form of a man so that they would be able to see him since no human being is capable of seeing an angel; and had We sent him down and made him a man We would have assuredly confused obscured for them what they are confusing for themselves when they say ‘This is but a mere mortal like the rest of you’.
