Abu Hurairah reported,

The Messenger of Allah ﷺ said, "The Children of Israil used to bathe naked, looking at one another, but the Prophet of Allah Musa عليه السلام was modest and reserved, and he would conceal himself when he bathed. So they slandered him, claiming there was a defect in his body."He continued, "One day, while the Prophet of Allah Musa عليه السلام was bathing, he placed his clothes on a rock, and the rock ran off with his clothes. The Prophet of Allah chased after it, striking at it with his staff and saying, 'My clothes, stone! My clothes, stone!' until it brought him to a gathering of the Children of Israil and stopped in their midst. Then the rock stood still, and the Prophet of Allah took his clothes. They looked at him and saw that he was the most beautifully formed of people and the most perfectly proportioned. The Children of Israil said, 'May Allah destroy the slanderers among the Children of Israil!' So this was his vindication, by which Allah عز وجل cleared him."

حدثنا حسين بن محمد في تفسير شيبان عن قتادة قال حدث الحسن

عن أبي هريرة

أن رسول الله ﷺ قال إن بني إسرائيل كانوا يغتسلون عراة وكان نبي الله موسى عليه السلام منه الحياء والستر وكان يستتر إذا اغتسل فطعنوا فيه بعورة قال فبينما نبي الله موسى عليه السلام يغتسل يوما وضع ثيابه على صخرة فانطلقت الصخرة بثيابه فاتبعها نبي الله ضربا بعصاه وهو يقول ثوبي يا حجر ثوبي يا حجر حتى انتهى به إلى ملإ من بني إسرائيل وتوسطهم فقامت وأخذ نبي الله ثيابه فنظروا فإذا أحسن الناس خلقا وأعدلهم صورة فقالت بنو إسرائيل قاتل الله أفاكي بني إسرائيل فكانت براءته التي برأه الله عز وجل بها
