and found some beads of Jewish workmanship that were not even worth two dirhams.

The incident of the poisoned sheep:
Layth ibn Saʿd narrated—through Saʿīd, from Abū Hurayrah—that when Khaybar was conquered a sheep laced with poison was presented to the Messenger of Allah ﷺ. He said, “Gather for me all the Jews who are here.” When they had been assembled he said, “I am going to ask you something; will you answer me truthfully?” They replied, “Yes, Abū al-Qāsim.” He asked, “Who is your father?” They said, “Our father is so-and-so.” He said, “You have lied; rather, your father is so-and-so.” They responded, “You have spoken the truth and done well.” He then said, “Will you speak truthfully if I question you about something else?” They said, “Yes, Abū al-Qāsim; and if we lie you will uncover our lie just as you have done concerning our lineage.” He asked, “Who are the people of the Fire?” They answered, “We shall be in it for only a short while, then you will replace us in it.” The Messenger of Allah ﷺ replied, “Stay disgraced in it! By Allah, we shall never replace you.” He then said, “Will you now tell me the truth?” They answered, “Yes.” He asked, “Did you put poison in this sheep?” They said, “Yes.” He asked, “What moved you to do that?” They said, “We wished—if you were an impostor—to be rid of you; but if you were a prophet, the poison would not harm you.” Al-Bukhārī recorded this report.

Khalid ibn al-Hārith said: Shuʿbah related to us, from Hishām ibn Zayd, from Anas, that a Jewish woman brought the Prophet ﷺ a poisoned sheep, and he ate from it. She was then brought before him, and he questioned her. She said, “I meant to kill you.” He replied, “Allah would never give you power to do that,” or he said, “over me.” They said, “Shall we kill her?” He said, “No.” Anas added, “I continued to notice the effect of that poison in the uvula of the Messenger of Allah ﷺ.” This wording is agreed upon.
