أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ هِشَامِ بْنِ حَسَّانَ، عَنْ أَبِي إِدْرِيسَ، قَالَ شَهِدْتُ أَنَسَ بْنَ مَالِكٍ أُتِيَ بِبُسْرٍ مُذَنَّبٍ فَجَعَلَ يَقْطَعُهُ مِنْهُ .
It was narrated that Abu Idris said: "I saw Anas bin Malik when some Busr which had extra bits were brought to him, and he started to cut them off."
