When al-Hasan was born, I named him Harb [which means war], then the Messenger of Allah ﷺ came and said: ʿShow me my son; what did you name him?ʿ We said: Harb. He said: ʿRather he is Hasan.” When al-Husain was born, I named him Harb, then the Messenger of Allah ﷺ came and said: “Show me my son; what did you name him?” We said; Harb. He said: “Rather he is Husain.” When the third one was born, I named him Harb. The Prophet ﷺ came and said: “Show me my son, what did you name him?” I said. Harb. He said: ʿRather, he is Muhassin.ʿ Then he said: ʿI have named them after the fashion of the sons of Haroon, Shabbar and Shabeer and Mushabbir.” (Using translation from Aḥmad 769)
لَمَّا وُلِدَ الْحَسَنُ سَمَّيْتُهُ حَرْبًا فَجَاءَ رَسُولُ اللهِ ﷺ فَقَالَ «أَرُونِي ابْنِي مَا سَمَّيْتُمُوهُ؟» فَقُلْتُ حَرْبًا فَقَالَ «بَلْ هُوَ حَسَنٌ» فَلَمَّا وُلِدَ الْحُسَيْنُ سَمَّيْناهُ حَرْبًا فَأَتَى رَسُولُ اللهِ ﷺ فَقَالَ «ائْتُونِي ابْنِي مَا سَمَّيْتُمُوهُ؟» فَقُلْتُ حَرْبًا فَقَالَ «بَلْ هُوَ حُسَيْنٌ» فَلَمَّا وُلِدَ الثَّالِثُ سَمَّيْتُهُ حَرْبًا فَجَاءَ رَسُولُ اللهِ ﷺ فَقَالَ «أَرُونِي ابْنِي مَا سَمَّيْتُمُوهُ؟» فَقُلْتُ حَرْبًا فَقَالَ «بَلْ هُوَ مُحَسِّنٌ» ثُمَّ قَالَ «إِنِّي سَمَّيْتُهُمْ بِأَسْمَاءِ وَلَدِ هَارُونَ شَبَرَ وَشُبَيْرَ وَمُشَبِّرَ»
