What is the reward for believing in Allah's divine decree and destiny, both good and bad, when deprived of children? Is this a decree of wrath or a test? Is it permissible to supplicate for a change in a predetermined decree? And what is the interpretation of "Marry the affectionate, fertile woman," and does this rule against marrying or settling down with someone who is not fertile?

Belief in divine decree (Qadar), both good and bad, is a fundamental pillar. Trials are an expiation for sins and a test of the sincerity of one's faith. A believer must be patient with Allah's decree and supplicate, for supplication does not contradict patience; rather, it is a weapon to ward off affliction. However, it is stipulated that the supplication must not be for something impossible, neither religiously nor rationally.
