All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
In Paradise, a woman gets pleasure only from one man just as a man takes pleasure in wives. So, there is no single wife in Paradise. Allah's Messenger said: “There are no single people in Paradise.” [Muslim]
Ibn Mandhoor said in Lisaan Al-‘Arab Lexicon: “The unmarried are those men and women who have no spouse.”
Allah Says (what means): {Indeed, We have produced the women of Paradise in a [new] creation; And made them virgins, Devoted [to their husbands] and of equal age,} [Quran 56:35-37]
This means that Allah, The Great and Almighty, will recreate the old women of the present life with eyes with white secretion and make them virgin and full of love for their mates. In other words, they become virgin, undefiled and full of love after they were deflowered, widowed and divorced. They show love, sweetness and elegance to their mates.
But, Allah, The Great and Almighty, honors man since He gave him women from this life and others from the Hereafter; i.e. Hour al-‘Ayn: damsels with large and black eyes. This, in fact, is a Divine favor which He gives to whom He likes. Anyway, Allah will grant all women and men in Paradise what they like. Allah Says (what means): {And therein is whatever the souls desire and [what] delights the eyes, and you will abide therein eternally.} [Quran 43: 71]
Here, it is suitable to refute the misconception that some people raise when they hear the above-mentioned verse. They say: “This verse indicates that if a woman likes to have sex with another man apart from her husband, Allah will help her to do so.” We reply: “It is not possible to find a woman (in Paradise) who likes to have sex with other than her husband.”
The following verse supports, such an opinion; Allah Says (what means): {In them are women limiting [their] glances, untouched before them by man or jinni -} [Quran 55:56]
Ibn 'Abbas and others said: “This verse means that women in Paradise lower their gaze except towards their husband. They do not see better than their husbands in Paradise.”
