Sudden peace upon him

A Jewess presented him at Khaybar with a roasted sheep which she had poisoned. The Apostle of Allah (peace be upon him) ate of it and the people also ate.He then said: Take away your hands (from the food), for it has informed me that it is poisoned. Bishr ibn al-Bara’ ibn Ma’rur al-Ansari died. So he (the Prophet) sent for the Jewess (and said to her): What motivated you to do the work you have done? She said: If you were a prophet, it would not harm you; but if you were a king, I should rid the people of you. The Apostle of Allah  then ordered regarding her and she was killed. He then said about the pain of which he died: I continued to feel pain from the morsel which I had eaten at Khaybar. This is the time when it has cut off my aorta.
