"‏ كَانَتْ بَنُو إِسْرَائِيلَ يَغْتَسِلُونَ عُرَاةً، يَنْظُرُ بَعْضُهُمْ إِلَى بَعْضٍ، وَكَانَ مُوسَى يَغْتَسِلُ وَحْدَهُ، فَقَالُوا وَاللَّهِ مَا يَمْنَعُ مُوسَى أَنْ يَغْتَسِلَ مَعَنَا إِلاَّ أَنَّهُ آدَرُ، فَذَهَبَ مَرَّةً يَغْتَسِلُ، فَوَضَعَ ثَوْبَهُ عَلَى حَجَرٍ، فَفَرَّ الْحَجَرُ بِثَوْبِهِ، فَخَرَجَ مُوسَى فِي إِثْرِهِ يَقُولُ ثَوْبِي يَا حَجَرُ‏.‏ حَتَّى نَظَرَتْ بَنُو إِسْرَائِيلَ إِلَى مُوسَى، فَقَالُوا وَاللَّهِ مَا بِمُوسَى مِنْ بَأْسٍ‏.‏ وَأَخَذَ ثَوْبَهُ، فَطَفِقَ بِالْحَجَرِ ضَرْبًا ‏"

The Prophet (ﷺ) said, 'The (people of) Bani Israel used to take bath naked (all together) looking at each other. The Prophet (ﷺ) 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."
