لَّا يَحِلُّ لَكَ ٱلنِّسَآءُ مِنۢ بَعْدُ وَلَآ أَن تَبَدَّلَ بِهِنَّ مِنْ أَزْوَٰجٍۢ وَلَوْ أَعْجَبَكَ حُسْنُهُنَّ إِلَّا مَا مَلَكَتْ يَمِينُكَ ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ رَّقِيبًۭا
It is not allowed thee to take (other) women henceforth, nor that thou shouldst change them for other wives even though their beauty pleased thee, save those whom thy right hand possesseth. And Allah is ever Watcher over all things.

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Exalted: "...O you who believe! Enter not the Prophet's houses, except when leave is given to you for a meal... (up to) ... Verily! With Allah that shall be an enormity." (V.33:53)
Narrated Anas bin Malik:
I of all the people know best this verse of Al-Hijab. When Allah's Messenger (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.
