What is the reason for Allah's lack of success in the life of a family, despite the parents' religious commitment, and what is the solution to this problem?

This world is a place of trial, and no one is spared from these trials. Whoever is tested by Allah and perseveres with patience, Allah will compensate them in the Hereafter. Allah Almighty says: (Indeed, the patient will be given their reward without account). And affliction in this world is not a sign of wretchedness; rather, a person is tried according to the strength of their faith. It may be for the expiation of sins, the elevation of ranks, the purification of believers, or a punishment for some transgressions. Among the greatest means of sustenance are abundant supplication and seeking forgiveness, coupled with diligence in pursuing means. And piety is a way out of every difficulty. Allah Almighty says: (And whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect).
