عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ لَمَّا وُلِدَ الْحَسَنُ سَمَّيْتُهُ حَرْبًا فَجَاءَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ أَرُونِي ابْنِي مَا سَمَّيْتُمُوهُ قَالَ قُلْتُ حَرْبًا قَالَ بَلْ هُوَ حَسَنٌ فَلَمَّا وُلِدَ الْحُسَيْنُ سَمَّيْتُهُ حَرْبًا فَجَاءَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ أَرُونِي ابْنِي مَا سَمَّيْتُمُوهُ قَالَ قُلْتُ حَرْبًا قَالَ بَلْ هُوَ حُسَيْنٌ فَلَمَّا وُلِدَ الثَّالِثُ سَمَّيْتُهُ حَرْبًا فَجَاءَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ أَرُونِي ابْنِي مَا سَمَّيْتُمُوهُ قُلْتُ حَرْبًا قَالَ بَلْ هُوَ مُحَسِّنٌ ثُمَّ قَالَ سَمَّيْتُهُمْ بِأَسْمَاءِ وَلَدِ هَارُونَ شَبَّرُ وَشَبِّيرُ وَمُشَبِّرٌ
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.
