One great blessing of paradise is that no-one has to strive to keep their husbands attention, after they have reached jannah. As a wife has to do in dunya. The spouses will be pure. And Allah has made paradise without any kind of sin. So the married couples will live an eternity of fidelity. Only the believers will enter paradise. So the believing husband and the believing wife will strive together in this world. Guard their eyes. Guard their tongues. Guard their private part. And help each other remain pure within their marriage, so they can reach paradise together. What a great achievement for those who strive, and doesn’t give up. Despite the temptation and fitnah of everyday life. Glad tidings to the strangers who have taqwa.
