Volume 5, Book 57, Number 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.”
