Narrated Abu Huraira:

The Prophet (s.a.w.a.) said, 'The (people of) Bani Israel used to take bath naked (all together) looking at each other. The Prophet (s.a.w.a.) Moses used to take a bath alone. They said, 'By Allah! Nothing prevents Moses from taking a bath with us except that he has a scrotal hernia.' So once Moses went out to take a bath and put his clothes over a stone and then that stone ran away with his clothes. Moses followed that stone saying, "My clothes, O stone! My clothes, O stone! till the people of Bani Israel saw him and said, 'By Allah, Moses has got no defect in his body. Moses took his clothes and began to beat the stone." Abu Huraira added, "By Allah! There are still six or seven marks present on the stone from that excessive beating."

Amongst the traditions narrated from Muhammad, the Messenger of Allah (s.a.w.a.) on the authority of Abu Huraira, the one is that Banu Isra'il used to take a bath naked, and they looked at the private parts of one another. Moses (peace be upon him), however, took a bath alone (in privacy) ; and they said (tauntingly):

By Allah, nothing prohibits Moses to take a bath along with us, but sacrotal hernia. He (Moses) once went for a bath and placed his clothes on a stone and the stone moved on with his clothes. Moses ran after it saying: 0 stone, my clothes,0 stone, my clothes, and Banu Isra'il had the chance to see the private parts of Moses, and said: By Allah, Moses does not suffer from any ailment. The stone then stopped, till Moses had been seen by them, and he then took hold of his clothes and struck the stone. Abu Huraira said: By Allah, there are the marks of six or seven strokes made by Moses on the stone.
