2120. Narrated Anas bin Mālik رضي الله عنه: While the Prophet ﷺ was in the market, somebody called, "O Abul-Qāsim." The Prophet ﷺ turned to him. The man said, "I have called to this (i.e., another man)." The Prophet ﷺ said, "Name yourselves by my name but not by my Kunya (surname)."(1) (In Arab world it is the custom to call the man as the father of his eldest son, e.g., Abul-Qāsim.)
