The Haya of the Prophet (SAW) (Hadith No. 360)
This is a very cute incident. Note that the Prophet (SAW) was very young at this time.
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.
Haya (modesty) has been an attribute of the Prophets. It is a part of Iman. I’ve covered this topic in the past. So read up:
Remember, no amount of haya is enough. The more the better. :)
