Al-Ahzab 33:56

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلَّا أَن يُؤْذَنَ لَكُمْ إِلَىٰ طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ وَلَـٰكِنْ إِذَا دُعِيتُمْ فَادْخُلُوا فَإِذَا طَعِمْتُمْ فَانتَشِرُوا وَلَا مُسْتَأْنِسِينَ لِحَدِيثٍ ۚ إِنَّ ذَٰلِكُمْ كَانَ يُؤْذِي النَّبِيَّ فَيَسْتَحْيِي مِنكُمْ ۖ وَاللَّهُ لَا يَسْتَحْيِي مِنَ الْحَقِّ ۚ وَإِذَا سَأَلْتُمُوهُنَّ مَتَاعًا فَاسْأَلُوهُنَّ مِن وَرَاءِ حِجَابٍ ۚ ذَٰلِكُمْ أَطْهَرُ لِقُلُوبِكُمْ وَقُلُوبِهِنَّ ۚ وَمَا كَانَ لَكُمْ أَن تُؤْذُوا رَسُولَ اللَّهِ وَلَا أَن تَنكِحُوا أَزْوَاجَهُ مِن بَعْدِهِ أَبَدًا ۚ إِنَّ ذَٰلِكُمْ كَانَ عِندَ اللَّهِ عَظِيمًا

O you who have believed, do not enter the houses of the Prophet except when you are permitted for a meal, without awaiting its readiness. But when you are invited, then enter; and when you have eaten, disperse without seeking to remain for conversation. Indeed, that [behavior] was troubling the Prophet, and he is shy of [dismissing] you. But Allah is not shy of the truth. And when you ask [his wives] for something, ask them from behind a partition. That is purer for your hearts and their hearts. And it is not [conceivable or lawful] for you to harm the Messenger of Allah or to marry his wives after him, ever. Indeed, that would be in the sight of Allah an enormity.

إِن تُبْدُوا شَيْئًا أَوْ تُخْفُوهُ فَإِنَّ اللَّهَ كَانَ بِكُلِّ شَيْءٍ عَلِيمًا

Whether you reveal a thing or conceal it, indeed Allah is ever, of all things, Knowing.

لَّا جُنَاحَ عَلَيْهِنَّ فِي آبَائِهِنَّ وَلَا أَبْنَائِهِنَّ وَلَا إِخْوَانِهِنَّ وَلَا أَبْنَاءِ إِخْوَانِهِنَّ وَلَا أَبْنَاءِ أَخَوَاتِهِنَّ وَلَا نِسَائِهِنَّ وَلَا مَا مَلَكَتْ أَيْمَانُهُنَّ ۗ وَاتَّقِينَ اللَّهَ ۚ إِنَّ اللَّهَ كَانَ عَلَىٰ كُلِّ شَيْءٍ شَهِيدًا

There is no blame upon women concerning their fathers or their sons or their brothers or their brothers' sons or their sisters' sons or their women or those their right hands possess. And fear Allah. Indeed Allah is ever, over all things, Witness.

إِنَّ الَّذِينَ يُؤْذُونَ اللَّهَ وَرَسُولَهُ لَعَنَهُمُ اللَّهُ فِي الدُّنْيَا وَالْآخِرَةِ وَأَعَدَّ لَهُمْ عَذَابًا مُّهِينًا

Indeed, those who abuse Allah and His Messenger - Allah has cursed them in this world and the Hereafter and prepared for them a humiliating punishment.

وَالَّذِينَ يُؤْذُونَ الْمُؤْمِنِينَ وَالْمُؤْمِنَاتِ بِغَيْرِ مَا اكْتَسَبُوا فَقَدِ احْتَمَلُوا بُهْتَانًا وَإِثْمًا مُّبِينًا

And those who harm believing men and believing women for [something] other than what they have earned have certainly born upon themselves a slander and manifest sin.

يَا أَيُّهَا النَّبِيُّ قُل لِّأَزْوَاجِكَ وَبَنَاتِكَ وَنِسَاءِ الْمُؤْمِنِينَ يُدْنِينَ عَلَيْهِنَّ مِن جَلَابِيبِهِنَّ ۚ ذَٰلِكَ أَدْنَىٰ أَن يُعْرَفْنَ فَلَا يُؤْذَيْنَ ۗ وَكَانَ اللَّهُ غَفُورًا رَّحِيمًا

O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves [part] of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allah Forgiving and Merciful.
