عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا أَنْزَلَ اللَّهُ دَاء إِلا أنزل لَهُ دَوَاء» . رَوَاهُ البُخَارِيّ

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.
