The death of the Prophet Muhammad PBUH (Who killed?)

Poisoned by a Jewess Muhammad was poisoned by a Jewish woman, following the conquest of Khaibar, where he took Safiyah as a wife, and ordered the torture and beheading of her husband Kinana, the chief of the Jews at Khaibar. Narrated Anas bin Malik: A Jewess brought a poisoned (cooked) sheep for the Prophet who ate from it. She was brought to the Prophet and he was asked, "Shall we kill her?" He said, "No." I continued to see the effect of the poison on the palate of the mouth of Allah's Apostle . Sahih Bukhari 3:47:786 ....Narrated 'Aisha: The Prophet in his ailment in which he died, used to say, "O 'Aisha! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison." Sahih Bukhari 5:59:713
