Hazrat Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Once I was sleeping, and in a dream I saw that people were being presented before me and they were wearing shirts. Some had shirts reaching up to their chests, and some had shirts lower than that. (Then) Umar bin Al-Khattab was brought before me. The shirt he was wearing, he was dragging it. (That is, his shirt was so long that it reached the ground.) The companions (may Allah be pleased with them) asked: O Messenger of Allah! What is the interpretation of this? The Prophet (peace and blessings be upon him) said: (It means) religion.
