Read and reflect on verse 3586 from Surah Al-Ahzaab: O YOU who have attained to faith! Do not enter the Prophet’s dwellings unless you are given leave; [and when invited] to a meal, do not come [so early...
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلَّا أَنْ يُؤْذَنَ لَكُمْ إِلَىٰ طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ وَلَٰكِنْ إِذَا دُعِيتُمْ فَادْخُلُوا فَإِذَا طَعِمْتُمْ فَانْتَشِرُوا وَلَا مُسْتَأْنِسِينَ لِحَدِيثٍ ۚ إِنَّ ذَٰلِكُمْ كَانَ يُؤْذِي النَّبِيَّ فَيَسْتَحْيِي مِنْكُمْ ۖ وَاللَّهُ لَا يَسْتَحْيِي مِنَ الْحَقِّ ۚ وَإِذَا سَأَلْتُمُوهُنَّ مَتَاعًا فَاسْأَلُوهُنَّ مِنْ وَرَاءِ حِجَابٍ ۚ ذَٰلِكُمْ أَطْهَرُ لِقُلُوبِكُمْ وَقُلُوبِهِنَّ ۚ وَمَا كَانَ لَكُمْ أَنْ تُؤْذُوا رَسُولَ اللَّهِ وَلَا أَنْ تَنْكِحُوا أَزْوَاجَهُ مِنْ بَعْدِهِ أَبَدًا ۚ إِنَّ ذَٰلِكُمْ كَانَ عِنْدَ اللَّهِ عَظِيمًا
O YOU who have attained to faith! Do not enter the Prophet’s dwellings unless you are given leave; [and when invited] to a meal, do not come [so early as] to wait for it to be readied: but whenever you are invited, enter [at the proper time]; and when you have partaken of the meal, disperse without lingering for the sake of mere talk: that, behold, might give offence to the Prophet, and yet he might feel shy of [asking] you [to leave]: but God is not shy of [teaching you] what is right. And [as for the Prophet’s wives,] whenever you ask them for anything that you need, ask them from behind a screen: this will but deepen the purity of your hearts and theirs. Moreover, it does not behove you to give offence to God’s Apostle - just as it would not behove you ever to marry his widows after he has passed away: that, verily, would be an enormity in the sight of God.
