Musannaf Ibn Abi Shaybah 15494 — What a person in ihram may kill

Sayyiduna Abu Sa'id (may Allah be pleased with him) said: A person in ihram may kill the snake, the scorpion, the attacking beast of prey, the biting dog and the little mouse. He was asked: Why was the mouse given the description 'al-fuwaysiqah' (the little wicked one)? He said: Because it was about to burn the house with a lamp wick when the eyes of the Prophet (peace and blessings be upon him) opened.
