'If you do not feel ashamed, do whatever you like."  

قَالَ النَّبِيُّ ﷺ إِنَّ مِمَّا أَدْرَكَ النَّاسَ مِنْ كَلاَمِ النُّبُوَّةِ إِذَا لَمْ تَسْتَحِ فَاصْنَعْ مَا شِئْتَ  

Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Faith consists of sixty (or seventy) branches. The best of them is 'There is no god but Allah.' The lowest of them is to remove harmful things from the road. Modesty is also a branch of faith."  

عَنِ النَّبِيِّ ﷺ قَالَ الإِيمَانُ بِضْعٌ وَسِتُّونَ أَوْ بِضْعٌ وَسَبْعُونَ شُعْبَةً أَفْضَلُهَا لاَ إِلَهَ إِلاَّ اللَّهُ وَأَدْنَاهَا إِمَاطَةُ الأَذَى عَنِ الطَّرِيقِ وَالْحَيَاءُ شُعْبَةٌ مِنَ الإيمَانِ  

Abu Sa'id said, "The Prophet, may Allah bless him and grant him peace, had more modesty than a virgin in her tent. When he disliked something, that could be seen in his face."  

سَمِعْتُ أَبَا سَعِيدٍ قَالَ كَانَ النَّبِيُّ ﷺ أَشَدَّ حَيَاءً مِنَ الْعَذْرَاءِ فِي خِدْرِهَا وَكَانَ إِذَا كَرِهَ شَيْئًا عَرَفْنَاهُ فِي وَجْهِهِ  

Sa'id ibn al-'As reported that 'Uthman and 'A'isha told him that Abu Bakr asked for permission to come in to the Messenger of Allah, may Allah bless him and grant him peace, while he was lying of 'A'isha's bed, wearing 'A'isha's woollen shirt. He gave Abu Bakr permission to enter while he was like that. he gave him what he needed and then Abu Bakr left. Then 'Umar, may Allah be pleased with him, asked for permission to come in and he gave him permission to come in while he was like that. He gave him what he needed and then 'Umar left. 'Uthman said, "Then I asked for permission to come in and he sat up and told 'A'isha, 'Take your garment.' I told him what I needed and then I left.' 'A'isha asked, 'Messenger of Allah, why did I see that you did not do for Abu Bakr and 'Umar what you did for 'Uthman?' The Messenger of Allah, may Allah bless him and grant him peace, said, ''Uthman is a modest man and I feared that if I gave him permission to come in while I was in that state he would not tell me what he needed.'"  

أَنَّ أَبَا بَكْرٍ اسْتَأْذَنَ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ مُضْطَجِعٌ عَلَى فِرَاشِ عَائِشَةَ لاَبِسًا مِرْطَ عَائِشَةَ فَأَذِنَ لأَبِي بَكْرٍ وَهُوَ كَذَلِكَ فَقَضَى إِلَيْهِ حَاجَتَهُ ثُمَّ انْصَرَفَ ثُمَّ اسْتَأْذَنَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ فَأَذِنَ لَهُ وَهُوَ كَذَلِكَ فَقَضَى إِلَيْهِ حَاجَتَهُ ثُمَّ انْصَرَفَ قَالَ عُثْمَانُ ثُمَّ اسْتَأْذَنْتُ عَلَيْهِ فَجَلَسَ وَقَالَ لِعَائِشَةَ اجْمَعِي إِلَيْكِ ثِيَابَكِ قَالَ فَقَضَيْتُ إِلَيْهِ حَاجَتِي ثُمَّ انْصَرَفْتُ قَالَ فَقَالَتْ عَائِشَةُ يَا رَسُولَ اللهِ لَمْ أَرَكَ فَزِعْتَ لأَبِي بَكْرٍ وَعُمَرَ رَضِيَ اللَّهُ عَنْهُمَا كَمَا فَزِعْتَ لِعُثْمَانَ؟ قَالَ رَسُولُ اللهِ ﷺ إِنَّ عُثْمَانَ رَجُلٌ حَيِيٌّ وَإِنِّي خَشِيتُ إِنْ أَذِنْتُ لَهُ وَأَنَا عَلَى تِلْكَ الْحَالِ أَنْ لاَ يَبْلُغَ إِلَيَّ فِي حَاجَتِهِ  

Anas ibn Malik reported that the Prophet, may Allah bless him and grant him peace, said, "Whenever there is modesty in a thing, it adorns it. Whenever there is outrage in a thing, it debases it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَا كَانَ الْحَيَاءُ فِي شَيْءٍ إِلاَّ زَانَهُ وَلاَ كَانَ الْفُحْشُ فِي شَيْءٍ إِلا شَانَهُ  

Salim reported from his father that the Messenger of Allah, may Allah bless him and grant him peace, passed by a man who berating his brother about his modesty. He told him, "Let him be. Modesty is part of faith."  

أَنَّ رَسُولَ اللهِ ﷺ مَرَّ بِرَجُلٍ يَعِظُ أَخَاهُ فِي الْحَيَاءِ فَقَالَ دَعْهُ فَإِنَّ الْحَيَاءَ مِنَ الإيمَانِ حَدَّثَنَا عَبْدُ اللهِ قَالَ حَدَّثَنِي عَبْدُ الْعَزِيزِ بْنُ أَبِي سَلَمَةَ عَنِ ابْنِ شِهَابٍ عَنْ سَالِمٍ عَنِ ابْنِ عُمَرَ قَالَ مَرَّ النَّبِيُّ ﷺ عَلَى رَجُلٍ يُعَاتِبُ أَخَاهُ فِي الْحَيَاءِ كَأَنَّهُ يَقُولُ أَضَرَّ بِكَ فَقَالَ دَعْهُ فَإِنَّ الْحَيَاءَ مِنَ الإِيمَانِ  

'A'isha said, "The Prophet was lying down in my room with his thigh uncovered when Abu Bakr asked for permission to enter. He gave him permission to enter, remaining as he was. Then 'Umar asked for permission to come in and he gave him permission, remaining as he was. Then 'Uthman asked for permission to enter and the Prophet, may Allah bless him and grant him peace, sat up and arranged his garment, and then he came in and spoke. When he left, I said, 'Messenger of Allah, Abu Bakr came in and you did not exert yourself nor concern yourself with him. Then 'Umar came in and you did not exert yourself nor concern yourself with him. Then 'Uthman came in and you sat up and arranged your garment.' He said, 'Should I not be modest before a man before whom the angels are modest?'"  

أَنَّ عَائِشَةَ قَالَتْ كَانَ النَّبِيُّ ﷺ مُضْطَجِعًا فِي بَيْتِي كَاشِفًا عَنْ فَخِذِهِ أَوْ سَاقَيْهِ فَاسْتَأْذَنَ أَبُو بَكْرٍ رَضِيَ اللَّهُ عَنْهُ فَأَذِنَ لَهُ كَذَلِكَ فَتَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ فَأَذِنَ لَهُ كَذَلِكَ ثُمَّ تَحَدَّثَ ثُمَّ اسْتَأْذَنَ عُثْمَانُ رَضِيَ اللَّهُ عَنْهُ فَجَلَسَ النَّبِيُّ ﷺ وَسَوَّى ثِيَابَهُ قَالَ مُحَمَّدٌ وَلاَ أَقُولُ فِي يَوْمٍ وَاحِدٍ فَدَخَلَ فَتَحَدَّثَ فَلَمَّا خَرَجَ قَالَ قُلْتُ يَا رَسُولَ اللهِ دَخَلَ أَبُو بَكْرٍ فَلَمْ تَهَشَّ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُمَرُ فَلَمْ تَهَشَّ وَلَمْ تُبَالِهِ ثُمَّ دَخَلَ عُثْمَانُ فَجَلَسْتَ وَسَوَّيْتَ ثِيَابَكَ؟ قَالَ أَلاَ أَسْتَحِي مِنْ رَجُلٍ تَسْتَحِي مِنْهُ الْمَلاَئِكَةُ؟
