وَعَنْهُ قَالَ: رُمِيَ سَعْدُ بْنُ مُعَاذٍ فِي أكحله فحمسه النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِيَدِهِ بِمِشْقَصٍ ثمَّ ورمت فحمسه الثَّانِيَة. رَوَاهُ مُسلم
He told that when Sa'id b. Mu'adh was shot in the median vein of his arm the Prophet with his own hand cauterized it with a broad arrow head. Afterwards it swelled up and he cauterized it a second time. Muslim transmitted it.
