Mukhtasar Muslim

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: I saw in a dream that people were being presented before me and they were wearing shirts. Some of their shirts reached up to their chests, and some were even shorter than that. Then 'Umar (may Allah be pleased with him) appeared, and he was wearing such a long shirt that it was dragging on the ground. The people asked: O Messenger of Allah! What is the interpretation of this? He (peace and blessings be upon him) replied: Religion.
