Is a woman permitted to seek divorce from her husband who does not care about religion to the extent she desires, based on the Hadith: "Any woman who asks her husband for divorce without any sound reason, the fragrance of Paradise will be forbidden to her"?

If the husband is religiously upright, observant of his duties, and abstaining from forbidden acts, then he is a righteous husband whom one should hold onto. His shortcomings in seeking knowledge, memorizing the Quran, or engaging in da'wah (inviting to Islam) are not justifications for seeking a divorce, as perfection has no limit. The wife can strive to achieve her religious goals herself by accompanying righteous women, attending lectures, and so on. Moreover, an intelligent woman can change her husband's habits. Thinking of divorce as an easy solution is a mistake that could lead to worse outcomes. Islamic law has forbidden seeking divorce except for a legitimate reason or due to distress and hardship, as in the hadith: "Any woman who asks her husband for divorce without any distress, the scent of Paradise will be forbidden to her." So, if there is no legitimate reason, it is not permissible for a woman to seek divorce. However, if there is a legitimate reason, such as her dislike of his religiosity or character, she is permitted to seek khul' (divorce at the wife's instance) by returning what he gave her. Therefore, the wife must fear Allah, treat her husband well, and be content with his righteousness and uprightness, even if he falls short in other perfections.
