Sahih al-Bukhari 4378, 4379

It is related that 'Ubaydullah ibn 'Abdullah ibn 'Utba said, "It reached us that Musyalima the Liar had arrived in Madina and was staying in the house of al-Harith's daughter. He was married to the daughter of al-Harith ibn Kurayz and she was the mother of 'Abdullah ibn 'Amir. The Messenger of Allah, may Allah bless him and grant him peace, went up to him with Thabit ibn Qays ibn Shammas. He was the one called the Orator of the Messenger of Allah, may Allah bless him and grant him peace. He had a piece of stick in his hand, and he stood before him and spoke to him. Musaylima said to him, 'If you wish, we will keep ourselves clear of you and this business if you then delegate it to us after you.' The Prophet, may Allah bless him and grant him peace, said, 'Even if you were to ask me for this stick, I would not give it you. I think that you are the one about whom I have been shown what I was shown. This is Thabit ibn Qays who will answer you on my behalf.' Then the Prophet, may Allah bless him and grant him peace,left." 'Ubaydullah ibn 'Abdullah said, "I asked 'Abdullah ibn 'Abbas about the dream of the Messenger of Allah, may Allah bless him and grant him peace, which he mentioned and Ibn 'Abbas said, 'It was mentioned to me that the Messenger of Allah, may Allah bless him and grant him peace, said, "While I was asleep, I saw two gold bracelets on my arm and they appalled me and I disliked them. Then I was given permission to blow them off, and I blew them off and they flew away. I interpreted them as two liars who could emerge." 'Ubaydullah said, "One of them was al-'Ansi who was killed by Fayruz in Yemen and the other was Musaylima the Liar."
