Is it permissible for a girl to pray to marry the one she loves in Paradise, and can she remain without a husband there if she finds no pleasure in marriage?

A Muslim must focus on what benefits them in this world and the hereafter, and their primary concern should be how to be removed from the Fire and enter Paradise, not worrying about the details of what they will have in Paradise. The supplications of the prophets and righteous people revolved around entering Paradise and being saved from the Fire. Therefore, preoccupation with the details of the delights of Paradise and the torments of the Fire is considered an transgression in supplication. If a Muslim enters Paradise, they will find therein delights that satisfy them and more, including marriage, for "there is no unmarried person in Paradise." The feelings of the people of Paradise should not be measured by the feelings of the people of this world, for what the soul may not desire in this world, it may desire in Paradise.
