It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him): When Khaybar was conquered, a poisoned goat was gifted to the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said:“Gather all the Jews who are here and bring them to me.”So they were all gathered before him. He (peace and blessings be upon him) said:“I am going to ask you something; will you answer me truthfully?”They said: Yes, O Abu al-Qasim! He (peace and blessings be upon him) asked:“Who is your ancestor?”They replied: So-and-so. He (peace and blessings be upon him) said:“You have lied; your ancestor is so-and-so.”At this, they said: You have spoken the truth and said correctly. The Messenger of Allah (peace and blessings be upon him) then said:“If I ask you something else, will you tell me the truth?”They said: Yes, and even if we lie, you will catch our lie, just as you caught our lie about our ancestor. He (peace and blessings be upon him) asked them:“Who are the people who will dwell in Hellfire?”They said: For a few days, we will remain in it, then you people will take our place. The Messenger of Allah (peace and blessings be upon him) said:“You will remain in it in humiliation; by Allah, we will never take your place in it.”He (peace and blessings be upon him) then said:“If I ask you one more thing, will you tell me the truth?”They said: Yes (certainly). So he (peace and blessings be upon him) said:“Did you put poison in this goat?”They said: Yes. He (peace and blessings be upon him) asked:“What prompted you to do this?”They said: Our intention was that if you were a liar, we would be rid of you, and if you were a true Prophet, then it would not harm you.
