He reported God's messenger as saying, "Moses was a modest man who kept himself covered, none of his skin being seen because pf modesty. Some of the B. Isra'il annoyed him by saying that he concealed himself to this extent only because of some skin trouble such as leprosy or a scrotal hernia, but God wished to clear him. So, one day when he was alone having a bath, he placed his garment on a stone and the stone flew away with his garment. Moses raced after it saying, `My garment, stone; my garment, stone,' till he came to a company of the B. Isra'il who, seeing him naked in the most beautiful form God had created, said, `We swear by God that there is nothing wrong with Moses.' He took his garment and began to beat the stone, and I swear by God that there were three, four, or five scars on the stone from the effect of his beating." (Bukhari and Muslim.)
