Surah Al-Ahzab Ayah #5 Translated in English

Assert their relationship to their fathers; this is more equitable with Allah; but if you do not know their fathers, then they are your brethren in faith and your friends; and there is no blame on you concerning that in which you made a mistake, but (concerning) that which your hearts do purposely (blame may rest on you), and Allah is Forgiving, Merciful.
