Messenger of Allah ﷺ said, "(The Prophet) Moses was a shy person and used to cover his body completely because of his extensive shyness. One of the children of Israel hurt him by saying, 'He covers his body in this way only because of some defect in his skin, either leprosy or scrotal hernia, or he has some other defect.' Allah wished to clear Moses of what they said about him, so one day while Moses was in seclusion, he took off his clothes and put them on a stone and started taking a bath. When he had finished the bath, he moved towards his clothes so as to take them, but the stone took his clothes and fled; Moses picked up his stick and ran after the stone saying, 'O stone! Give me my garment!' Till he reached a group of Bani Israel who saw him naked then, and found him the best of what Allah had created, and Allah cleared him of what they had accused him of. The stone stopped there and Moses took and put his garment on and started hitting the stone with his stick. By Allah, the stone still has some traces of the hitting, three, four or five marks. This was what Allah refers to in His Saying:-- "O you who believe! Be you not like those Who annoyed Moses, But Allah proved his innocence of that which they alleged, And he was honorable In Allah's Sight." (33.69)  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ مُوسَى كَانَ رَجُلاً حَيِيًّا سِتِّيرًا لاَ يُرَى مِنْ جِلْدِهِ شَىْءٌ اسْتِحْيَاءً مِنْهُ فَآذَاهُ مَنْ آذَاهُ مِنْ بَنِي إِسْرَائِيلَ فَقَالُوا مَا يَسْتَتِرُ هَذَا التَّسَتُّرَ إِلاَّ مِنْ عَيْبٍ بِجِلْدِهِ إِمَّا بَرَصٌ وَإِمَّا أُدْرَةٌ وَإِمَّا آفَةٌ وَإِنَّ اللَّهَ أَرَادَ أَنْ يُبَرِّئَهُ مِمَّا قَالُوا لِمُوسَى فَخَلاَ يَوْمًا وَحْدَهُ فَوَضَعَ ثِيَابَهُ عَلَى الْحَجَرِ ثُمَّ اغْتَسَلَ فَلَمَّا فَرَغَ أَقْبَلَ إِلَى ثِيَابِهِ لِيَأْخُذَهَا وَإِنَّ الْحَجَرَ عَدَا بِثَوْبِهِ فَأَخَذَ مُوسَى عَصَاهُ وَطَلَبَ الْحَجَرَ فَجَعَلَ يَقُولُ ثَوْبِي حَجَرُ ثَوْبِي حَجَرُ حَتَّى انْتَهَى إِلَى مَلإٍ مِنْ بَنِي إِسْرَائِيلَ فَرَأَوْهُ عُرْيَانًا أَحْسَنَ مَا خَلَقَ اللَّهُ وَأَبْرَأَهُ مِمَّا يَقُولُونَ وَقَامَ الْحَجَرُ فَأَخَذَ ثَوْبَهُ فَلَبِسَهُ وَطَفِقَ بِالْحَجَرِ ضَرْبًا بِعَصَاهُ فَوَاللَّهِ إِنَّ بِالْحَجَرِ لَنَدَبًا مِنْ أَثَرِ ضَرْبِهِ ثَلاَثًا أَوْ أَرْبَعًا أَوْ خَمْسًا فَذَلِكَ قَوْلُهُ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَكُونُوا كَالَّذِينَ آذَوْا مُوسَى فَبَرَّأَهُ اللَّهُ مِمَّا قَالُوا وَكَانَ عِنْدَ اللَّهِ وَجِيهًا}  

that the Prophet ﷺ said: "Verily Musa, peace be upon him, was a shy and modest man, who would never show anything of his skin out of modesty. Some of the Children of Isra'il annoyed him by saying: 'He only keeps himself covered because of some defect in his skin, either leprosy, a scrotal hernia or some other defect.' Allah [the Mighty and Sublime] wanted to free Musa from what they were saying about him. One day Musa, [peace be upon him], was alone. He took off his garment, and put it on a rock, then he took a bath. When he had finished, he turned back to pick up his garment, but the rock moved away, taking his garment with it. Musa picked up his staff, and chased the rock saying: 'My garment, O you rock! My garment, O you rock!' Until he reached a group of the Children of Isra'il who saw him naked, and discovered that he was the best of those whom Allah had created." He said: "The rock stood still, he took his garment and put it on. He started striking the rock with his staff, and by Allah, the marks of that beating were left on the rock; three, four, or five. This is what is referred to in the Ayah: ' O you who believe! Be not like those who annoyed Musa, but Allah freed him from what they had alleged, and he was honourable before Allah (33:69).'" (Using translation from Tirmidhī 3221)   

عَنِ النَّبِيِّ ﷺ وَخِلَاسٌ وَمُحَمَّدٌ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ فِي هَذِهِ الْآيَةِ {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَكُونُوا كَالَّذِينَ آذَوْا مُوسَى فَبَرَّأَهُ اللهُ مِمَّا قَالُوا} [الأحزاب 69] قَالَ قَالَ رَسُولُ اللهِ ﷺ إِنَّ مُوسَى كَانَ رَجُلًا حَيِيًّا سِتِّيرًا لَا يَكَادُ يُرَى مِنْ جِلْدِهِ شَيْءٌ اسْتِحْيَاءً مِنْهُ قَالَ فَآذَاهُ مَنْ آذَاهُ مِنْ بَنِي إِسْرَائِيلَ قَالُوا مَا يَتَسَتَّرُ هَذَا التَّسَتُّرَ إِلَّا مِنْ عَيْبٍ بِجِلْدِهِ إِمَّا بَرَصٍ وَإِمَّا أُدْرَةٍ وَقَالَ رَوْحٌ مَرَّةً أُدْرَةً وَإِمَّا آفَةً وَإِنَّ اللهَ ﷻ أَرَادَ أَنْ يُبَرِّئَهُ مِمَّا قَالُوا وَإِنَّ مُوسَى خَلَا يَوْمًا فَوَضَعَ ثَوْبَهُ عَلَى حَجَرٍ ثُمَّ اغْتَسَلَ فَلَمَّا فَرَغَ أَقْبَلَ إِلَى ثَوْبِهِ لِيَأْخُذَهُ وَإِنَّ الْحَجَرَ عَدَا بِثَوْبِهِ فَأَخَذَ مُوسَى عَصَاهُ وَطَلَبَ الْحَجَرَ وَجَعَلَ يَقُولُ ثَوْبِي حَجَرُ ثَوْبِي حَجَرُ حَتَّى انْتَهَى إِلَى مَلَإٍ مِنْ بَنِي إِسْرَائِيلَ فَرَأَوْهُ عُرْيَانًا كَأَحْسَنِ الرِّجَالِ خَلْقًا وَأَبْرَأَهُ مِمَّا كَانُوا يَقُولُونَ لَهُ وَقَامَ الْحَجَرُ فَأَخَذَ ثَوْبَهُ وَطَفِقَ بِالْحَجَرِ ضَرْبًا بِعَصَاهُقَالَ فَوَاللهِ إِنَّ فِي الْحَجَرِ لَنَدَبًا مِنْ أَثَرِ ضَرْبِهِ ثَلَاثًا أَوْ أَرْبَعًا أَوْ خَمْسًا  

"إِنَّ موسى كان رجلا حَيِيًّا سِتِّيرًا لَا يُرَى من جِلْدِه شَئ استحياءً منه، فَآذَاهُ مَنْ آذاه من بنى إِسرائيل فقالوا: ما يستتر هَذَا التَّسَتُّرَ إِلا من عيبٍ بجلده، إِما بَرَصٌ، وإِما أُدْرَةٌ وإِما أَفَةٌ، وإِنَّ اللَّه ﷻ أَرَادَ أَن يُبَرِّئه مما قَالُوا بموسى فَخَلَا يَوْمًا وحدَه فوضع ثِيَابَهُ عَلَى الْحَجَرِ ثم أغْتَسل فلما فَرَغ أَقْبَل إِلى ثيابِه ليأخذَها وإِنَّ الحجر عَدَا بِثَوْبه فأَخذَ موسى عصاه، وطلبَ الحجرَ فجعل يقول: ثوبى حَجَرُ. (ثوبى حجرُ) حتى انْتَهَى إِلى مَلأَ من بنى إِسرائيلَ، فَرَأَوْهُ عُرْيَانًا أَحْسَنَ ما خلقَه اللَّه وَأَبْرَأَهُ مِمَّا يَقُولون، وَأَقَام الْحَجَر، فأَخذ ثوبهَ فَلبسه وطفِقَ بالحجر ضَرْبًا بعصاه، فواللَّه إِنَّ بالحجرِ لَنَدْبًا مِنْ أَثر ضَرْبِهِ ثَلاثًا أَو أَربعًا أَوْ خَمْسا فذلك قوله تعالى {يَاأَيُّهَا الَّذِينَ آمَنُوا لَا تَكُونُوا كَالَّذِينَ آذَوْا مُوسَى فَبَرَّأَهُ اللَّهُ مِمَّا قَالُوا وَكَانَ عِنْدَ اللَّهِ وَجِيهًا} .
