Anas bin Malik narrated:
"The Messenger of Allah (s.a.w) said:'Indeed Messenger-ship and Prophethood have been terminated, so there shall be no Messenger after me, nor a Prophet.'" He(Anas) said:"The people were concerned about that, so he (s.a.w) said: 'But there will be Mubash-shirat.' So they said: 'O Messenger of Allah! What is Mubash-shirat?' He said: 'The Muslim's dreams, for it is a portion of the portions of Prophethood.'" (FR)
