What is the wisdom behind the exclusive assignment of the Houriyyat to men in Paradise?

Question:
Another brother asks a question and says: Why did Allah promise men in Paradise the Houriyyat, but did not promise the women anything of that? May Allah reward you with good.

Answer:
The wisdom in that—and Allah knows best—is that men are the maintainers of women, and that if they are promised these things, it becomes closer to motivating them in seeking the Hereafter, striving to seek the Hereafter, and not being content with this world in a way that prevents them from racing to do good deeds. And women are generally followers of men.
So if a man is granted the Houriyyat in Paradise, along with the great good and the high ranks in Paradise that Allah promised the believing women, they will have a reward that makes them wives of the righteous men in Paradise. The man is given an additional share of the Houriyyat, and there is no harm, no competition, and no co-wife rivalry in Paradise, as co-wives do in this world.
