Using the word "law" (if only) when good is missed

Question:
That Allah is the one who creates and forgives him. What is the purpose of the salam? It is that one must perform an action in some cases, and this person does not realize the realities, and he believes in the divine decree of Allah. Some of it is from the perspective of sincerity, and some is the most capable action in terms of sincerity.

Answer:
"Law" (if only) is of two types. If it is used to express regret over missing out on good, there is no harm in it, because this indicates eagerness for good, and "I would have made it an 'Umrah and would not have been sad with him." This is from the perspective of regretting good. This indicates the perfection of faith and the truthfulness of faith: that when a person misses something of good, he regrets it and feels broken. This is a sign of good. As for the one who, whenever he misses good or an 'Umrah, this is evidence of weak faith or the absence of faith. As for the "law" used for lamentation and dissatisfaction, that is the prohibited one. And this is what is obligatory: if something befalls you, do not say it in a way that implies dissatisfaction. This is if one says it from the perspective of dissatisfaction with the divine decree and destiny of Allah. This is what is prohibited. Yes. If Allah wills.
