The wives of the Prophet ﷺ out of their jealousy, backed each other against the Prophet, so I said to them, "It may be, if he divorced you all, that Allah will give him, instead of you wives better than you." So this Verse was revealed. (66.5)
عُمَرُ ؓ اجْتَمَعَ نِسَاءُ النَّبِيِّ ﷺ فِي الْغَيْرَةِ عَلَيْهِ فَقُلْتُ لَهُنَّ عَسَى رَبُّهُ إِنْ طَلَّقَكُنَّ أَنْ يُبَدِّلَهُ أَزْوَاجًا خَيْرًا مِنْكُنَّ فَنَزَلَتْ هَذِهِ الآيَةُ
[Machine] Omar ibn Al-Khattab said, "The wives of the Messenger of Allah ﷺ gathered together in jealousy of him." So I said, "Perhaps if he divorces you, his Lord will replace you with better wives than you." [Al-Tahrim 5] Then a similar verse was revealed.
قَالَ عُمَرُ بْنُ الْخَطَّابِ «اجْتَمَعَ عَلَى رَسُولِ اللهِ ﷺ نِسَاؤُهُ فِي الْغَيْرَةِ عَلَيْهِ» فَقُلْتُ {عَسَى رَبُّهُ إِنْ طَلَّقَكُنَّ أَنْ يُبْدِلَهُ أَزْوَاجًا خَيْرًا مِنْكُنَّ} [التحريم 5] فَنَزَلَتْ مِثْلَ ذَلِكَ
