Abu Huraira reported Allah's Messenger as saying: When any one of you fights with his brother he should avoid striking at the face.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا الْمُغِيرَةُ، - يَعْنِي الْحِزَامِيَّ - عَنِ أَبِي، الزِّنَادِ عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا قَاتَلَ أَحَدُكُمْ أَخَاهُ فَلْيَجْتَنِبِ الْوَجْهَ " .
