Naming a child after its mother

Q 2: In our village, some elders name the son after its mother and not its father. What is the ruling on this?

(Part No. 20; Page No. 367)  A: It is obligatory to name a child after its father, and it is not permissible to name it after its mother, for Allah (Exalted be He) states: Call them (adopted sons) by (the names of) their fathers: that is more just with Allâh. If the child's father is unknown, it should be given any suitable name such as `Abdullah, `Abd Al-Rahman or the like. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
