The Messenger of Allah ﷺ said, "The Children of Israil used to bathe naked, looking at one another's private parts, while the Prophet of Allah ﷺ was modest and reserved and would cover himself when bathing. So they criticized him and mocked him for it.One day, while the Prophet of Allah was bathing, he placed his clothes on a rock. The rock then ran off with them, and the Prophet of Allah chased after it, striking it with his staff and crying, 'My clothes, stone! My clothes, stone!' until it brought him to a gathering of the Children of Israil and stopped in their midst. There it came to a halt, and the Prophet of Allah took his clothes. They saw him as the most beautifully formed and well-proportioned of people.The gathering said, 'May Allah destroy the slanderers among the Children of Israil!' That was the vindication by which Allah cleared him."
حدثنا روح حدثنا سعيد وعبد الوهاب عن سعيد عن قتادة عن الحسن
أن رسول الله ﷺ قال إن بني إسرائيل كانوا يغتسلون عراة وكان نبي الله ﷺ فيه الحياء والخفر فكان يستتر إذا اغتسل فطعنوا فيه يعيروه قال فبينما نبي الله يغتسل يوما إذ وضع ثيابه على صخرة فانطلقت الصخرة فاتبعها نبي الله ضربا بالعصا ثوبي يا حجر ثوبي يا حجر حتى انتهت به إلى ملإ من بني إسرائيل وتوسطتهم فقامت فأخذ نبي الله ثيابه فنظروا إلى أحسن الناس خلقا وأعدلهم صورة فقال الملأ قاتل الله أفاكي بني إسرائيل فكانت براءته التي برأه الله
