Ṣaḥīḥ al-Bukhārī & Ṣaḥīḥ Muslim

Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Mūsa was a bashful man who used to cover his skin completely out of extreme bashfulness. So some of the children of Israel abused him, saying: 'His keenness on covering his body in this way is only because of some defect in his skin, either leprosy or scrotal hernia, or he has some other defect.' Allah wished to clear Mūsa of what they said about him.

So, one day, while Mūsa was alone, he took off his clothes and put them on a stone and started bathing. When he finished, he went to get his clothes but the stone ran away with them. Mūsa picked up his stick and ran after the stone saying: 'My garment, O stone! My garment, O stone!' He ran behind it until he reached a group of the Children of Israel who saw him naked then, and found him the best of what Allah had created, and thus Allah cleared him of what they had accused him of.

The stone stopped there and Mūsa took his garment, put it on and struck the stone repeatedly with his stick. By Allah, the effect of the strikes was visible on the stone; three, four, or five marks. This was what Allah refers to in His Saying: {O you who have believed, be not like those who abused Moses; then Allah cleared him of what they said. And he, in the sight of Allah , was distinguished.} [Sūrat al-Ahzāb: 69]"
