Then came the poisoning incident, after the conquest of Khaybar. Al-Bukhaari (2617) and Muslim (2190) narrated from Anas that a Jewish woman came to the Messenger of Allaah (peace and blessings of Allaah be upon him) with some poisoned mutton. The Messenger of Allaah (peace and blessings of Allaah be upon him) ate from it, then he asked her about that. She said, “I wanted to kill you.” He said, “Allaah would not let you do that.” They said, “Shall we kill her?” He said, “No.” He said, I can still see the effect of that on the palate of the Messenger of Allaah (peace and blessings of Allaah be upon him). Al-Nawawi said: It is as if the poison still left some trace of blackness etc. The name of this woman was Zaynab bint al-Haarith, the wife of Salaam ibn Mashkam, one of the leaders of the Jews. The reports differ as to whether or not she was killed. It seems that the Prophet (peace and blessings of Allaah be upon him) did not kill her at first, but when Bishr ibn al-Bara’ ibn Ma’roor died as a result of the effects of this food, then he executed her as a qisaas punishment.
