Hazrat Qasim bin Nafi states that Hazrat Umar said: If an unbridled animal causes any damage, there will be no liability on its owner, but if someone causes harm to an unbridled animal, that person will be held liable.

Hazrat Amr narrates that Hasan Basri and Hazrat Ibn Sirin were both asked about an animal that had been set free and caused harm to someone. Both of them replied that there would be no liability upon its owner.

Hazrat Ash'ath narrates that Hazrat 'Amir Sha'bi said: In the case of any harm caused by a freed animal, its owner will be held liable.

Hazrat Shu’bah states that Hazrat Hammad gave a ruling regarding a person whose animal broke free from its reins and ran away, causing harm to someone while the person was searching for it. He said: There will be no liability upon him, and Hazrat Hakam also gave the same ruling.
