Quran 43.18-20
(Liken they then to Allah) that which is bred up in outward show, and in dispute cannot make itself plain? And they make the angels, who are the slaves of the Beneficent, females. Did they witness their creation? Their testimony will be recorded and they will be questioned. And they say: If the Beneficent One had (so) willed, we should not have worshipped them. They have no knowledge whatsoever of that. They do but guess.
