It is narrated from Sayyiduna Amr bin Yathribi al-Damri (may Allah be pleased with him) that he said: I was present at the sermon of the Messenger of Allah (peace and blessings be upon him) at Mina. In the sermon he (peace and blessings be upon him) said: "The wealth of his brother is not lawful for anyone except what he gives willingly." When he (the narrator) heard this, he said: O Messenger of Allah, what is your view if I come across my cousin's sheep, take one sheep and slaughter it; is there anything upon me for that? He (peace and blessings be upon him) said: "If you find a ewe, say in Khabt al-Jamish, in a desolate land, and you are carrying a knife or some tool, even then do not touch it." It was said that it is a desolate place between Makkah and al-Jar where no one lives.
