Mukhtasar Bukhari (Abridged) 22 — Believers excel each other in deeds

Narrated Abu Sa'id Al-Khudri (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: "While I was sleeping, I saw (in a dream) that people were being presented before me and they were wearing shirts. Some shirts reached only up to their chests, and some were even shorter, and 'Umar bin Al-Khattab (may Allah be pleased with him) was also presented before me, and the shirt he was wearing was so long that he was dragging it (as he walked)." The Companions (may Allah be pleased with them) asked, "O Messenger of Allah! How did you interpret it?" He (peace and blessings of Allah be upon him) replied: "(The shirt) means religion."
