Allah tells us that His blessed, believing servants will have a good final return in the Hereafter, which means their ultimate destination. Then He explains it further, as He says:
In verse 52, it was said: وَعِندَهُمْ قَاصِرَاتُ الطَّرْفِ أَتْرَابٌ (and in their company there will be females restricting their glances ] to their husbands, and[ of matching ages.). Meant by these are the Hurs or Houris of Jannah (referred to, fondly enough for some people, even as 'nymphs of Paradise' ). Being of matching ages could mean that they will be of the same age as among themselves. And it could also mean that they will be of the same age as their spouses. In the first situation, if they were of the same age, the good thing. about it would be that they would be relating to each other in mutual amity as friends, and not as 'the other woman' something very welcome for spouses.
Consideration of matching age between spouses is better
Then there is the other situation. If being of the same age is taken to mean that spouses will be of the same age, the good thing about it would be that there would be temperamental harmony between them, and they will have consideration for each other's preferences. This tells us that consideration should be made to keep ages of spouses matched, for it generates mutual love, and makes the relationship of marriage pleasant and permanent.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 48–53
For which special assignment does God choose messengers from amongst human beings? The special mission of prophets entails that they make men aware of the fact that their real destination is the Hereafter, and that they should prepare themselves for it. This is the most crucial problem for man, one which warrants utter seriousness.
