Say: God is One, The Eternal God. He begot none, nor was He begotten. None is equal to Him.

(112:1-4)

Mankind, worship your Lord, who has created you and those before you so that you may ward off evil; who has made the earth a couch for you and the sky a canopy; and has sent down water from the sky, thereby producing fruits for you to eat. So do not knowingly set up rivals to God.

(2:21-22)

God forgives not that partners should be ascribed unto Him. He forgives whom He will all other sins. Whoever ascribes partners unto God has strayed far from the truth.

(4:116)
