Sahih Muslim | Book 26 | Hadith Number 5547

Narrated by Nafi'
Nafi' reported that Ibn 'Urnar used to kill all types of snakes until Abu Lubaba b. 'Abd al- Mundhir Badri reported that Allah's Messeng

er (may peace be upon him) had forbidden the killing of the snakes of the houses, and so he abstained from it.
