Sahih al-Bukhari 4016

Arabic

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ نَافِعٍ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ كَانَ يَقْتُلُ الْحَيَّاتِ كُلَّهَا‏.‏ حَتَّى حَدَّثَهُ أَبُو لُبَابَةَ الْبَدْرِيُّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنْ قَتْلِ جِنَّانِ الْبُيُوتِ، فَأَمْسَكَ عَنْهَا‏.‏

English translation

Narrated Nafi`:Ibn `Umar used to kill all kinds of snakes until Abu Lubaba Al-Badri told him that the Prophet (ﷺ) had forbidden the killing of harmless snakes living in houses and called Jinnan. So Ibn `Umar gave up killing them
