وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى قَالَ: قَالَ أَبُو لَيْلَى: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " إِذَا ظَهَرَتِ الْحَيَّةُ فِي الْمَسْكَنِ فَقُولُوا لَهَا: إِنَّا نَسْأَلُكِ بِعَهْدِ نُوحٍ وَبِعَهْدِ سُلَيْمَانَ بْنِ دَاوُدَ أَنْ لَا تُؤْذِينَا فَإِنْ عَادَتْ فَاقْتُلُوهَا ". رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ
