What did the Prophet Muhammad (peace be upon him) do when Al-`Abbas suggested that he take off his Izar and put it over his shoulders underneath the stones while they were building the Ka`ba?
 Narrated Jabir bin `Abdullah:                     While Allah's Apostle was carrying stones (along) with the people of Mecca for (the building of) the Ka`ba wearing an Izar (waist-sheet cover), his uncle Al-`Abbas said to him, "O my nephew! (It would be better) if you take off your Izar and put it over your shoulders underneath the stones." So he took off his Izar and put it over his shoulders, but he fell unconscious and since then he had never been seen naked.
