All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and messenger.
First of all, we ask Allaah to relieve you from your grief and distress, and reconcile between you and your husband. We recommend you to supplicate to Allaah as the hearts are in the Hands of Allaah and He turns them the way He wishes. If you think that your husband is most likely afflicted by magic and so on, then you should perform Ruqyah; for more information, please refer to Fatwa 92025.
It should be known that love is not a requirement for the establishment of marital life, as love may exist after it not having existed.
If a husband does not love his wife, it is not permissible that lack of love between spouses causes the husband to prevent his wife from her right in sexual intercourse as this involves injustice to her. So, you should advise him in a gentle and soft manner in this regard. In addition to this, you should beautify yourself for him and do whatever makes his heart attached to you.
In any case, if he insists on divorce, then you should submit all affairs to Allaah, as He may bring good in divorce and bless you with a better husband. Allaah says (what means): {But if they separate [by divorce], Allaah will enrich each [of them] from His abundance. And ever is Allaah Encompassing and Wise.} [Quran 4:130]
On the other hand, if the wife is upright – is not Naashiz (recalcitrant) – and she does not want to be separated from her husband, then he is not permitted to force her to give him compensation in return for divorcing her [such as with Khul']. Allaah says (what means): {O you who have believed, it is not lawful for you to inherit women by compulsion. And do not make difficulties for them in order to take [back] part of what you gave them unless they commit a clear immorality. And live with them in kindness. For if you dislike them - perhaps you dislike a thing and Allaah makes therein much good.} [Quran 4:19]
For more information on the rulings of Khul’ in Islam, please refer to Fatwa 89039 and 165253.
Allaah Knows best.
