Ibn Mas'ud reported God's messenger as saying, "Kill all the snakes, and he who fears their revenge does not belong to me." Abu Dawud and Nasa'i transmitted it.

وَعَنِ ابْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «اقْتُلُوا الْحَيَّاتِ كُلَّهُنَّ فَمَنْ خَافَ ثَأْرَهُنَّ فَلَيْسَ مِنِّي» . رَوَاهُ أَبُو دَاوُدَ وَالنَّسَائِيُّ
