name them after their fathers that is more just with allah. if you do not know their fathers regard them as your brothers in the religion or those under your sponsorship. there is no fault in you if you make mistakes but only in what your hearts intended. allah is forgiving and the most merciful the prophet has a greater right on the believers than their own selves his wives are their mothers. kinsmen are closer to one another in the book of allah than to other believers and the emigrants although you should act honorably towards those you sponsor that is written in the book
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 النبي أولى بالمؤمنين من أنفسهم وأزواجه أمهاتهم وأولو الأرحام بعضهم أولى ببعض في كتاب الله من المؤمنين والمهاجرين إلا أن تفعلوا إلى أوليائكم معروفا كان ذلك في الكتاب مسطورا
