Would marriage be blessed after marrying a girl with whom there is currently a love relationship, and her mother knows about it, given the current unavailability of means for marriage and its postponement until money is collected, and is this relationship not blessed by Allah?

It is advisable to turn to Allah with supplication for success in marrying the girl if there is good in it, while remembering that Allah is the Planner. One must repent from forbidden relationships before marriage, as they may deprive it of blessings. If the marriage does not take place, there are many women, and Allah may compensate with something better. One should choose a wife who is religious and of good character, as she will be a source of blessings, and facilitating the marriage is among the reasons for its blessings.
