Chapter 34: Chapters On Dreams
Abu Umamah bin Sahl bin Hunaif narrated from some of the companions of the Prophet (s. a. w) that the Prophet (s. a. w) said: "While I was sleeping I saw people presented before me, and that they were wearing shirts. Some of them (the shirts) reaching their breasts, and some of them reaching below that." He said: "Then 'Umar was presented before me and he was wearing a shirt that was dragging." They said: "How did you interpret that O Messenger of Allah?" He said: "The religion."
