That Ali bin Abi Talib said: "The Messenger of Allah ﷺ had the 'Aqiqah for Al-Hasan with one sheep, and said: 'O Fatimah! Shave his head and give the weight of his hair in silver as charity.'" He said: "So I weighed it, and it was the weight of a Dirham or a bit of a Dirham."  

عَقَّ رَسُولُ اللَّهِ ﷺ عَنِ الْحَسَنِ بِشَاةٍ وَقَالَ يَا فَاطِمَةُ احْلِقِي رَأْسَهُ وَتَصَدَّقِي بِزِنَةِ شَعْرِهِ فِضَّةً قَالَ فَوَزَنَتْهُ فَكَانَ وَزْنُهُ دِرْهَمًا أَوْ بَعْضَ دِرْهَمٍ
