Sayyiduna Amr bin Yathribi (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) addressed us in a sermon and said: "Beware! Nothing of his brother's property is lawful for a person, except what is given with his consent." I said: "O Messenger of Allah! What is your view: if I see my cousin's goats, may I take one goat from them (to slaughter)?" The Prophet (peace and blessings be upon him) said: "If you come upon it as a ewe carrying a knife and fire-flints at Khabt al-Jamish, even then do not touch it!" The narrator says: Khabt al-Jamish refers to a place between Makkah and al-Jar where there are no people. In his (Ahmad's) version it is "bi-janb" like this; he did not say "bi-khabt".
