Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: I saw people in a dream, they were coming before me, they were wearing shirts, some shirts reached up to their chests and some below that. When Umar ibn al-Khattab (may Allah be pleased with him) passed before me, his shirt (because of its length) was dragging on the ground. The companions asked: O Messenger of Allah! How did you interpret this? The Prophet (peace and blessings be upon him) said: Religion.
