Choosing A Name For Oneself
The Prophet (peace and blessings of Allaah be upon him) said: “Whoever calls himself by other than his fathers name (or attributes himself to someone other than his father), will be cursed by Allaah, the angels and all the people.” (Reported by Ibn Maajah, 2599; see also Saheeh al-Jaami, 6104). Call them (adopted sons) by the names of their fathers” [al-Ahzaab 33:5].
