Does the husband sin by divorcing his wife, who demands a separate home due to frequent problems with his family, especially given his awareness of his family's injustice towards her, and his punishment of his wife first with silence and then with divorce, knowing that the wife is obedient to him and no problems have occurred between them except those caused by his family?

It is not possible to definitively state that a husband is sinful if he divorces his wife, as that depends on the reason for the divorce, and the opinions of both spouses must be heard. If the husband divorces for a reason not considered religiously valid, then the ruling on divorce oscillates between prohibition, disliking (makrooh), and permissibility (mubah), and scholars have differed on this matter. Some consider it prohibited because it causes harm without need, while others consider it disliked or permissible based on the Prophet's (peace be upon him) saying: "The most hated of permissible things to Allah is divorce."
