Haram bin Sa'd bin Muhayyisah (may Allah have mercy on him) says that a she-camel of Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) entered the orchard of some people and damaged it. He (peace and blessings be upon him) gave judgement concerning it that "the owners of property must guard their property themselves (by day); if an animal damages crops at night, the owner of the animal is liable."
