It is narrated from Sayyiduna Ali, may Allah be pleased with him, who says: When Hasan was born, I named him Harb. The Messenger of Allah, peace and blessings be upon him, came and said: Show me my son, what name have you given him? I said: Harb. He said: No, rather his name is Hasan. Then when Husayn was born, I named him Harb. The Messenger of Allah, peace and blessings be upon him, came and said: Show me my son, what name have you given him? I said: Harb. The Messenger of Allah, peace and blessings be upon him, said: No, rather his name is Husayn. When the third child was born, I named him Harb. The Noble Prophet, peace and blessings be upon him, came and said: Show me my son, what name have you given him? I said: Harb. The Messenger of Allah, peace and blessings be upon him, said: No, rather he is Muhsin. Then the Messenger of Allah, peace and blessings be upon him, said: I have named these children after the names of the children of Harun, peace be upon him. Their names were: Shabbir, Shabbir, and Mushabbir.
