Companions of the Prophet

Bukhari :: Book 5 :: Volume 57 :: Hadith 40

Narrated Abu Said Al-Khudri:

I heard Allah's Apostle saying, "While I was sleeping, the people were presented to me (in a dream). They were wearing shirts, some of which were merely covering their (chests). and some were a bit longer. 'Umar was presented before me and his shirt was so long that he was dragging it." They asked, "How have you interpreted it, O Allah's Apostle?" He said, "Religion."
