Abu Hurairah reported,

Musa was a modest man who would never be seen unclothed. The Children of Israil said, "He must have some defect in his body."One day he went to bathe at a small pool of water and placed his garment on a stone. The stone took off running with it, and Musa chased after it with his staff, striking at it and crying out, "My garment, stone! My garment, stone!" until the stone finally stopped before a gathering of the Children of Israil.Then this verse was revealed, "You who believe, do not be like those who insulted Musa, but Allah cleared him of what they said, and he was held in honor with Allah" [Ahzab 33:69].

و حدثنا يحيى بن حبيب الحارثي حدثنا يزيد بن زريع حدثنا خالد الحذاء عن عبد الله بن شقيق قال أنبأنا

أبو هريرة قال

كان موسى عليه السلام رجلا حييا قال فكان لا يرى متجردا قال فقال بنو إسرائيل إنه آدر قال فاغتسل عند مويه فوضع ثوبه على حجر فانطلق الحجر يسعى واتبعه بعصاه يضربه ثوبي حجر ثوبي حجر حتى وقف على ملإ من بني إسرائيل ونزلت {يا أيها الذين آمنوا لا تكونوا كالذين آذوا موسى فبرأه الله مما قالوا وكان عند الله وجيها}
