Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) said: A Jewish woman of Khaybar gave him (peace and blessings be upon him) poisoned meat as a gift. He (peace and blessings be upon him) took the foreleg from it and ate it, and a group also ate with him (peace and blessings be upon him). He (peace and blessings be upon him) immediately said: "Hold back your hands." He (peace and blessings be upon him) summoned that Jewish woman and asked: "Did you put poison in this?" The woman said: "Who told you?" He (peace and blessings be upon him) said: "This foreleg told me." She said: "Yes, I did." He (peace and blessings be upon him) asked: "Why?" She said: "If you truly are a prophet, nothing will happen to you, and if you are not a prophet, we will be relieved of you." He (peace and blessings be upon him) pardoned her. Some of the Companions (may Allah be pleased with them) died because of that meat. He (peace and blessings be upon him) also had himself cupped between his shoulders to remove the effect of that poison; Abu Hind cupped him (peace and blessings be upon him) with a horn and a blade, and he was a freed slave of Banu Bayadah of the Ansar.
