Sayyiduna Anas bin Malik (may Allah be pleased with him) said: A Jewish woman presented a poisoned roasted goat to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) ate from it. She was brought to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) asked her about it. She said: I intended to kill you. He (peace and blessings be upon him) said: "Allah Almighty will not give you power over me (that is, you cannot destroy me)." The Companions (may Allah be pleased with them) asked: Shall we not kill her? He (peace and blessings be upon him) said: "No." The narrator said: I continued to notice it in the uvula, that is, the throat, of the Prophet (peace and blessings be upon him).
