عَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنْ تَرَكَ الْحَيَّاتِ مَخَافَةَ طَلْبِهِنَّ فَلَيْسَ مِنَّا، مَا سَالَمْنَاهُنَّ مُنْذُ حَارَبْنَاهُنَّ))
Narrated by Sayyiduna Abdullah bin Abbas, may Allah be pleased with them both, that the Messenger of Allah, peace and blessings be upon him, said: Whoever refrains from killing a snake out of fear of its retaliation is not one of us. Since our battle with them began, we have not made peace with them.
