It was narrated that Abu Sa’eed Al-Khudri said: “The Prophet passed by a man who was dragging a sheep by its ear. He said: ‘Leave its ear alone and hold it by the sides of its neck.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عُقْبَةُ بْنُ خَالِدٍ، عَنْ مُوسَى بْنِ مُحَمَّدِ بْنِ إِبْرَاهِيمَ التَّيْمِيِّ، أَخْبَرَنِي أَبِي، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ مَرَّ النَّبِيُّ ـ صلى الله عليه وسلم ـ بِرَجُلٍ وَهُوَ يَجُرُّ شَاةً بِأُذُنِهَا فَقَالَ " دَعْ أُذُنَهَا وَخُذْ بِسَالِفَتِهَا " .
