Quran 6:8 — Livestock (Al-An'am)

They also said, "If only an angel could come down with him!" Had we sent an angel, the whole matter would have been terminated, and they would no longer be respited.

[6:7] Even if we sent down to them a physical book, written on paper, and they touched it with their hands, those who disbelieved would have said, "This is no more than clever magic."

[6:9] Had we sent an angel, we would have sent him in the form of a man, and we would have kept them just as confused as they are confused now.
