Bearing the name Khalafallah

Q: What is the ruling on the proper name "Khalafallah"? Some of my fellow Muslims told me that it is not legally permitted to be called Khalafallah because Allah (Exalted be He) has no successors. Therefore, I went to the concerned bodies in the civilian affairs in order to change my name from Khalafallah to Khalaf. (Part No. 11; Page No. 471) But they asked me to bring a legal Fatwa that mentions that the name of Khalafallah is not legally recommended. I would like you to help me in changing my name in order to relieve myself of this disturbance and to please Allah (Exalted be He).

A: If what is meant by the name "Khalafallah" 'one who succeeds Allah and comes after Him,' then this name is not legally permitted. But if what is meant by such name 'a child who is a gift and a grant from Allah to His servant that compensates a previous grant,' then it will be a lawful name. This is what appears sound to us. Consequently, you are not in need of changing your name.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
