Nafi' reported that Abu Lubaba talked to Ibn 'Umar to open a door in his house which would bring them nearer to the mosque and they found a fresh slough of the snake, whereupon 'Abdullah said:Find it out and kill it. Abu Lubaba said: Don't kill them, for Allah's Messenger (ﷺ) forbade the killing of the snakes found in houses.
وَحَدَّثَنِي مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، ح وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَاللَّفْظُ، لَهُ حَدَّثَنَا لَيْثٌ، عَنْ نَافِعٍ، أَنَّ أَبَا لُبَابَةَ، كَلَّمَ ابْنَ عُمَرَ لِيَفْتَحَ لَهُ بَابًا فِي دَارِهِ يَسْتَقْرِبُ بِهِ إِلَى الْمَسْجِدِ فَوَجَدَ الْغِلْمَةُ جِلْدَ جَانٍّ فَقَالَ عَبْدُ اللَّهِ الْتَمِسُوهُ فَاقْتُلُوهُ . فَقَالَ أَبُو لُبَابَةَ لاَ تَقْتُلُوهُ فَإِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ قَتْلِ الْجِنَّانِ الَّتِي فِي الْبُيُوتِ .
