call them by their fathers that will be most equitable in the sight of allah. and if ye know not their fathers then they are your brethren in religion and your friends. and there is no fault upon you in regard to the mistake ye have made therein but in regard to that which your hearts intend purposely. and allah is ever forgiving merciful.
ادعوهم لآبائهم هو أقسط عند الله فإن لم تعلموا آباءهم فإخوانكم في الدين ومواليكم وليس عليكم جناح فيما أخطأتم به ولكن ما تعمدت قلوبكم وكان الله غفورا رحيما
