Not the Son of Allah
They say, “Allah has taken a son.” Glory be to Him! He is self-sufficient. Everything in the heavens and the earth belongs to Him. You have no proof for this. Are you saying about Allah what you do not know?
2:116And they say: Allah hath taken unto Himself a son. Be He glorified! Nay, but whatsoever is in the heavens and the earth is His. All are subservient unto Him.
10:68They say: Allah hath taken (unto Him) a son - Glorified be He! He hath no needs! His is all that is in the heavens and all that is in the earth. Ye have no warrant for this. Tell ye concerning Allah that which ye know not?
