Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 56. Virtues and Merits of the Prophets (PBUH) and his Companions
Narated By Ibn Abbas : Musailama-al-Kadhdhab (i.e. the liar) came in the life-time of Allah's Apostle with many of his people (to Medina) and said, "If Muhammad makes me his successor, I will follow him." Allah's Apostle went up to him with Thabit bin Qais bin Shams; and Allah's Apostle was carrying a piece of a date-palm leaf in his hand. He stood before Musailama (and his companions) and said, "If you asked me even this piece (of a leaf), I would not give it to you. You cannot avoid the fate you are destined to, by Allah. If you reject Islam, Allah will destroy you. I think that you are most probably the same person whom I have seen in the dream." Abu Huraira told me that Allah's Apostle; said, "While I was sleeping, I saw (in a dream) two gold bracelets round my arm, and that worried me too much. Then I was instructed divinely in my dream, to blow them off and so I blew them off, and they flew away. I interpreted the two bracelets as symbols of two liars who would appear after me. And so one of them was Al-Ansi and the other was Musailama Al-Kadhdhab from Al-Yamama."
