Okut

Ahmed Raza Khan: Mohammed Aqib Qadri:
Call them with their fathers' names - this is more suitable in the sight of Allah; and if you do not know their fathers, then they are your brothers in the faith, (and your cousins as humans) and your friends; and there is no sin upon you for what you did unknowingly in the past - however it is a sin what you do with your heart's intention; and Allah is Oft Forgiving, Most Merciful.
