Five are the beasts for killing which there is no sin for the Muhrim: crows, kites, scorpions, rats and wild dogs.
Sahih Muslim Book 15, Hadith 82
← Previous Hadith A person asked Ibn 'Umar which beast a Muhrim could kill, whereupon he said: One of the wives of Allahs Apostle (ﷺ) told me: He (the Holy Prophet) commanded to kill voracious dog, rat, scorpion, kite, crow, and snake (and this is allowed) likewise in prayer.

Sahih Muslim Book 15, Hadith 81 Next Hadith → I said to Nafi: What is that which you heard Ibn, Umar declaring permissible for a Muhrim to kill some of the beasts? Nafi, said to me that 'Abdullah had reported: I heard Allah's Messenger (ﷺ) as saying: Five are the beasts in killing which or their being killed, there is no sin: crow, kite, scorpion, rat and voracious dog.
