Abu Saeed Khudri reported,

The Prophet ﷺ said, "While I was asleep, I saw people being presented before me, wearing shirts. Some of the shirts reached the breast, and some fell below that. Then Umar was presented before me, wearing a shirt that he was dragging along."They asked, "What did you interpret it to mean, Messenger of Allah?"He replied, "Religion."He said, and this is more authentic.
