Narrated Abdullah ibn Abbas:

The Prophet ﷺ said: He who leaves the snakes along through fear of their pursuit, does not belong to us. We have not made peace with them since we have fought with them.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، حَدَّثَنَا مُوسَى بْنُ مُسْلِمٍ، قَالَ سَمِعْتُ عِكْرِمَةَ، يَرْفَعُ الْحَدِيثَ فِيمَا أُرَى إِلَى ابْنِ عَبَّاسٍ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" مَنْ تَرَكَ الْحَيَّاتِ مَخَافَةَ طَلَبِهِنَّ فَلَيْسَ مِنَّا مَا سَالَمْنَاهُنَّ مُنْذُ حَارَبْنَاهُنَّ " .
