‘The one in Ihram may kill the snake, the scorpion, the aggressive predator, the vicious dog and the harmful mouse.” It was said to him: “Why is it said that they are harmful?” He said:* “Because the Messenger of Allah (ﷺ) woke up because of one, and it had taken the wick (of the lamp) to burn down the house.”
Sunan Ibn Majah Book 25, Hadith 208
← Previous Hadith “There are five animals, for which there is no sin on a person if he kills them” – or he said: “if he kills them when in Ihram – the scorpion, the crow, the kite, the mouse and the vicious dog.”

Sunan Ibn Majah Book 25, Hadith 207 Next Hadith → “Sa;b bin Jaththamah told us: ‘The Messenger of Allah (ﷺ) passed by me when I was in Abwa’ or Waddan, and I gave him some meat of a wild donkey, but he gave it back to me, and when he saw from my face that I was upset, he said: ‘The only reason that we are giving it back is that we are in Ihram.’”
