18:81
فَ أَرَدْ نَآ أَن يُبْدِلَ هُمَا رَبُّ هُمَا خَيْرًا مِّنْ هُ زَكَوٰةً وَ أَقْرَبَ رُحْمًا
So we intended that their Lord should substitute for them one better than him in purity and nearer to mercy.
66:5
عَسَىٰ رَبُّ هُۥٓ إِن طَلَّقَ كُنَّ أَن يُبْدِلَ هُۥٓ أَزْوَٰجًا خَيْرًا مِّن كُنَّ مُسْلِمَٰتٍ مُّؤْمِنَٰتٍ قَٰنِتَٰتٍ تَٰٓئِبَٰتٍ عَٰبِدَٰتٍ سَٰٓئِحَٰتٍ ثَيِّبَٰتٍ وَ أَبْكَارًا
Perhaps his Lord, if he divorced you [all], would substitute for him wives better than you - submitting [to Allah], believing, devoutly obedient, repentant, worshipping, and traveling - [ones] previously married and virgins.
68:32
عَسَىٰ رَبُّ نَآ أَن يُبْدِلَ نَا خَيْرًا مِّنْ هَآ إِنَّ آ إِلَىٰ رَبِّ نَا رَٰغِبُونَ
Perhaps our Lord will substitute for us [one] better than it. Indeed, we are toward our Lord desirous."
