33:5Call them after their fathers; that is more equitable with God. But if you do not know their fathers, then your brethren in faith and your friends. There is no blame on you if you err therein, barring what your hearts premeditates. God is Forgiving and Merciful.

33:40Muhammad is not the father of any of your men; but he is the Messenger of God, and the seal of the prophets. God is Cognizant of everything.

33:55There is no blame on them concerning their fathers, or their sons, or their brothers, or their brothers’ sons, or their sisters’ sons, or their women, or their female servants. But they should remain conscious of God. God is Witness over all things.
