The Prophet ﷺ said, "If somebody fights (or beats somebody) then he should avoid the face."  

عَنِ النَّبِيِّ ﷺ قَالَ: «إِذَا قَاتَلَ أَحَدُكُمْ فَلْيَجْتَنِبِ الْوَجْهَ۔»  

I heard Jabir bin ʿAbdullah saying, "A man passed through the mosque carrying arrows. Allah's Apostle said to him, 'Hold them by their heads.' "  

مَرَّ رَجُلٌ فِي الْمَسْجِدِ وَمَعَهُ سِهَامٌ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ: «أَمْسِكْ بِنِصَالِهَا۔»  

The Prophet ﷺ said, "If anyone of you passed through our mosque or through our market while carrying arrows, he should hold the iron heads," or said, "..... he should hold (their heads) firmly with his hand lest he should injure one of the Muslims with it."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا مَرَّ أَحَدُكُمْ فِي مَسْجِدِنَا أَوْ فِي سُوقِنَا وَمَعَهُ نَبْلٌ فَلْيُمْسِكْ عَلَى نِصَالِهَا أَوْ قَالَ فَلْيَقْبِضْ بِكَفِّهِ أَنْ يُصِيبَ أَحَدًا مِنَ الْمُسْلِمِينَ مِنْهَا شَىْءٌ
