Sayyiduna Ali (may Allah be pleased with him) narrates: When Hasan was born, I named him Harb. The Prophet (peace and blessings be upon him) came and said: Show me my son, what name have you given him? We said: Harb. The Prophet (peace and blessings be upon him) said: No, rather he is Hasan. Then when Husayn was born, I named him Harb. The Prophet (peace and blessings be upon him) came and said: Show me my son, what name have you given him? We said: Harb. The Prophet (peace and blessings be upon him) said: No, rather he is Husayn. Then when a third child was born to me, I named him Harb. The Prophet (peace and blessings be upon him) came and said: Show me my son, what name have you given him? We said: We have named him Harb. The Prophet (peace and blessings be upon him) said: No, rather he is Muhsin. Then the Prophet (peace and blessings be upon him) said: I name them after the children of Sayyiduna Harun (peace be upon him): Shabbar, Shabbir, and Mushbir.
