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.  

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  

I of all the people know best this verse of Al-Hijab. When Messenger of Allah ﷺ married Zainab bint Jahsh she was with him in the house and he prepared a meal and invited the people (to it). They sat down (after finishing their meal) and started chatting. So the Prophet ﷺ went out and then returned several times while they were still sitting and talking. So Allah revealed the Verse: 'O you who believe! Enter not the Prophet's houses until leave is given to you for a meal, (and then) not (so early as) to wait for its preparation .....ask them from behind a screen.' (33.53) So the screen was set up and the people went away.  

أَنَسُ بْنُ مَالِكٍ أَنَا أَعْلَمُ النَّاسِ بِهَذِهِ الآيَةِ آيَةِ الْحِجَابِ لَمَّا أُهْدِيَتْ زَيْنَبُ إِلَى رَسُولِ اللَّهِ ﷺ كَانَتْ مَعَهُ فِي الْبَيْتِ صَنَعَ طَعَامًا وَدَعَا الْقَوْمَ فَقَعَدُوا يَتَحَدَّثُونَ فَجَعَلَ النَّبِيُّ ﷺ يَخْرُجُ ثُمَّ يَرْجِعُ وَهُمْ قُعُودٌ يَتَحَدَّثُونَ فَأَنْزَلَ اللَّهُ تَعَالَى {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلاَّ أَنْ يُؤْذَنَ لَكُمْ إِلَى طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ} إِلَى قَوْلِهِ {مِنْ وَرَاءِ حِجَابٍ} فَضُرِبَ الْحِجَابُ وَقَامَ الْقَوْمُ  

[Machine] "I am the most knowledgeable of people or the most knowledgeable of people regarding the verse of Hijab. The Prophet ﷺ married Zainab bint Jahsh and slaughtered a sheep, then he called his companions and they ate and sat talking. The Prophet ﷺ would go out and enter while they were sitting, then he would go out and stay for as long as Allah wished, and he would return while they were sitting, and Zainab would be sitting in a corner of the house. The Prophet ﷺ felt shy to say anything to them, so the verse was revealed: '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' [Surah Al-Ahzab, verse 53] The verses continued until the statement 'and ask them from behind a partition' [Surah Al-Ahzab, verse 53]. So the Messenger of Allah ﷺ commanded the Hijab to be in place and it was struck."  

أَنَا أَعْلَمُ النَّاسِ أَوْ مِنْ أَعْلَمِ النَّاسِ بِآيَةِ الْحِجَابِ تَزَوَّجَ النَّبِيُّ ﷺ زَيْنَبَ ابْنَةَ جَحْشٍ فَذَبَحَ شَاةً فَدَعَا أَصْحَابَهُ فَأَكَلُوا وَقَعَدُوا يَتَحَدَّثُونَ وَجَعَلَ النَّبِيُّ ﷺ يَخْرُجُ وَيَدْخُلُ وَهُمْ قُعُودٌ ثُمَّ يَخْرُجُ فَيَمْكُثُ مَا شَاءَ اللهُ وَيَرْجِعُ وَهُمْ قُعُودٌ وَزَيْنَبُ قَاعِدَةٌ فِي نَاحِيَةِ الْبَيْتِ وَجَعَلَ النَّبِيُّ ﷺ يَسْتَحْيِي مِنْهُمْ أَنْ يَقُولَ لَهُمْ شَيْئًا فَنَزَلَتْ {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوابُيُوتَ النَّبِيِّ إِلَّا أَنْ يُؤْذَنَ لَكُمْ إِلَى طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ وَلَكِنْ إِذَا دُعِيتُمْ فَادْخُلُوا} [الأحزاب 53] الْآيَاتُ إِلَى قَوْلِهِ ﷻ {فَاسْأَلُوهُنَّ مِنْ وَرَاءِ حِجَابٍ} [الأحزاب 53] قَالَ فَأَمَرَ رَسُولُ اللهِ ﷺ بِالْحِجَابِ مَكَانَهُ فَضُرِبَ
