'Ali said, "When al-Husayn was born, I named him Harb (war). The Prophet came and said, 'Show me your son. What have you named him?' 'Harb,' we replied. He said, "He is Hasan.' When al-Husayn was born, I named him Harb. The Prophet ﷺ came and said, 'Show me your son. What have you named him?' 'Harb,' we replied. He said, "He is Husayn.' When we had a third son, I named him Harb. The Prophet ﷺ came and said, 'Show me your son. What have you named him?' 'Harb,' we replied. He said, "He is Muhassin." Then he said, 'I have named them according to the names of the sons of Harun:
Shabr, Shubayr, and Mushabbir.'"

حَدَّثَنَا أَبُو نُعَيْمٍ، عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنْ هَانِئِ بْنِ هَانِئٍ، عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: لَمَّا وُلِدَ الْحَسَنُ رَضِيَ اللَّهُ عَنْهُ سَمَّيْتُهُ: حَرْبًا، فَجَاءَ النَّبِيُّ ﷺ فَقَالَ: أَرُونِي ابْنِي، مَا سَمَّيْتُمُوهُ؟ قُلْنَا: حَرْبًا، قَالَ: بَلْ هُوَ حَسَنٌ. فَلَمَّا وُلِدَ الْحُسَيْنُ رَضِيَ اللَّهُ عَنْهُ سَمَّيْتُهُ حَرْبًا، فَجَاءَ النَّبِيُّ ﷺ فَقَالَ: أَرُونِي ابْنِي، مَا سَمَّيْتُمُوهُ؟ قُلْنَا: حَرْبًا، قَالَ: بَلْ هُوَ حُسَيْنٌ. فَلَمَّا وُلِدَ الثَّالِثُ سَمَّيْتُهُ: حَرْبًا، فَجَاءَ النَّبِيُّ ﷺ فَقَالَ: أَرُونِي ابْنِي، مَا سَمَّيْتُمُوهُ؟ قُلْنَا: حَرْبًا، قَالَ: بَلْ هُوَ مُحْسِنٌ، ثُمَّ قَالَ: إِنِّي سَمَّيْتُهُمْ بِأَسْمَاءِ وَلَدِ هَارُونَ: شِبْرٌ، وَشَبِيرٌ، وَمُشَبِّرٌ.
