Ibn `Umar used to kill snakes but when Abu Lubaba informed him that the Prophet (ﷺ) had forbidden the killing of snakes living in houses, he gave up killing them.
Sahih al-Bukhari Book 59, Hadith 119
← Previous Hadith Ibn `Umar used to kill snakes, but afterwards he forbade their killing and said, "Once the Prophet (ﷺ) pulled down a wall and saw a cast-off skin of a snake in it. He said, 'Look for the snake. 'They found it and the Prophet (ﷺ) said, "Kill it." For this reason I used to kill snakes. Later on I met Abu Lubaba who told me the Prophet (ﷺ) said, 'Do not kill snakes except the short-tailed or mutilated-tailed snake with two white lines on its back, for it causes abortion and makes one blind. So kill it.' "

Sahih al-Bukhari Book 59, Hadith 118 Next Hadith → The Prophet (ﷺ) said, "Five kinds of animals are mischief-doers and can be killed even in the Sanctuary: They are the rat the scorpion, the kite (a type of predatory bird), the crow and the rabid dog."
