Narrated 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 datepalm 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.
