In the Name of Allāh.
One of the eternal ecstasies of Paradise promised to the righteous believers is having spouses; cute and equal in age. Allāh says (in Surah Yasin [36] verse 56): “They and their wives will be in pleasant shade, reclining on thrones.”
One should know that the righteous couples (i.e. married men and women) who died upon Islamic Monotheism in this world shall be in Paradise. Allāh says (in Surah Az-Zukhruf [43] verse 70): “Enter Paradise, you and your wives, in happiness.”
Then, the men (of Paradise) shall additionally be granted newly created houris (pure maidens) of Paradise. Allāh says (in Surah Al-Waqi’ah [56] verses 35-37): “Verily, We have created them (maidens) of special creation. And made them virgins. Loving (their husbands only), equal in age.”
Therefore, why should a believing man prevent himself from the immediate special treats by the houris of Jannah, due to Zina (unlawful sexual relations) with a woman of this world who is not up to snuff to those damsels? Why would a believing woman also prefer to let go of her husband in Paradise, due to the same crime? We need to reflect! The delight in Paradise is real, thus, we need to believe.
I beseech Allāh to grant us His Paradise and not deprive us of its inherent pleasures. (Aameen)
