Imam Malik's Muwatta, Chapter: Judgements

Yahya said that he heard Malik say, "What is done in our community about injury to a domestic animal, is that the one who injures it must pay the amount by which he has diminished the animal's price." Yahya said that he heard Malik speak about a camel who attacked a man and he feared for himself and killed it or hamstrung it. He said, "If he has a clear proof that it was heading for him and had attacked him, there are no damages against him. If there is no clear proof except his word, he is responsible for the camel."
