Narrated Ibn `Abbas:

Musailima Al-Kadhdhab came during the lifetime of the Prophet (ﷺ) and started saying, "If Muhammad gives me the rule after him, I will follow him." And he came to Medina with a great number of the people of his tribe. Allah's Messenger (ﷺ) went to him in the company of Thabit bin Qais bin Shammas, and at that time, Allah's Messenger (ﷺ) had a stick of a date-palm tree in his hand. When he (i.e. the Prophet (ﷺ) ) stopped near Musailima while the latter was amidst his companions, he said to him, "If you ask me for this piece (of stick), I will not give it to you, and Allah's Order you cannot avoid, (but you will be destroyed), and if you turn your back from this religion, then Allah will destroy you. And I think you are the same person who was shown to me in my dream, and this is Thabit bin Qais who will answer your questions on my behalf." Then the Prophet (ﷺ) went away from him.
