Mukhtasar Bukhari

Narrated Jabir (may Allah be pleased with him): I went out with the Prophet (peace and blessings of Allah be upon him) on one of his journeys. One night, due to a need of mine, I came to him and found him praying. I had a cloth over my body, so I wrapped it tightly around myself and stood by his side and prayed as well. When he finished, he said: "O Jabir! What brings you at this hour of the night?" I told him my need. When I was done, the Prophet (peace and blessings of Allah be upon him) said: "What was that wrapping of the cloth that I saw?" I said: It was a single cloth. So the Prophet (peace and blessings of Allah be upon him) said: "If the cloth is wide, then wrap yourself in it, and if it is tight, then make it an izar (lower garment or waist-wrapper)."
