Sahih Muslim Book - 43, Hadith - 6147

وَحَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، حَدَّثَنَا خَالِدٌ الْحَذَّاءُ ، عَنْ عَبْدِ اللهِ بْنِ شَقِيقٍ ، قَالَ : أَنْبَأَنَا أَبُو هُرَيْرَةَ ، قَالَ : كَانَ مُوسَى عَلَيْهِ السَّلاَمُ رَجُلاً حَيِيًّا ، قَالَ فَكَانَ لاَ يُرَى مُتَجَرِّدًا ، قَالَ فَقَالَ : بَنُو إِسْرَائِيلَ: إِنَّهُ آدَرُ ، قَالَ : فَاغْتَسَلَ عِنْدَ مُوَيْهٍ ، فَوَضَعَ ثَوْبهُ عَلَى حَجَرٍ ، فَانْطَلَقَ الْحَجَرُ يَسْعَى ، وَاتَّبَعَهُ بِعَصَاهُ يَضْرِبُهُ : ثَوْبِي ، حَجَرُ ثَوْبِي ، حَجَرُ حَتَّى وَقَفَ عَلَى مَلَأٍ مِنْ بَنِي إِسْرَائِيلَ وَنَزَلَتْ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَكُونُوا كَالَّذِينَ آذَوْا مُوسَى فَبَرَّأَهُ اللَّهُ مِمَّا قَالُوا وَكَانَ عِنْدَ اللهِ وَجِيهًا}.

It was narrated that ‘Abdullah bin Shaqiq said: Abu Hurairah told us: “Musa, was a shy man, and he was never seen naked. The Children of Israel said: ‘He has a scrotal hernia.’ He bathed in a pound and put his garment on rock. The rock sped off, and he chased it with his stick, striking it and saying: ‘My garment, O rock! My garment, O rock!’ until it stopped near a group of the Children of Israel. Then the Verse: ‘O you who believe! Be not like those who annoyed Musa, but Allah cleared of him that which they alleged, and he was honorable before Allah was revealed.”
