All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The basic principle is that a woman is Islamically forbidden from asking for divorce from her husband or Khul’ except for a sound Islamic justification.
Thawbaan narrated that the Prophet said: “Any woman who asks her husband for a divorce without a sound reason, the smell of Paradise is forbidden to her.” [Abu Dawood]
One of the justifications for requesting divorce is harm. If your husband’s circumstances prevent him from joining you except after a period of time during which you are harmed while waiting for him, then it is permissible for you to ask for divorce on the grounds of harm.
Khul’ is also prescribed in the event that a woman hates her husband and is afraid of not fulfilling his right; so it is permissible for her to request Khul’ in exchange for compensation to be paid to her husband, as the woman of Thaabit Ibn Qays did and her story was narrated by Al-Bukhari in his Saheeh.
We advise you not to rush for seeking divorce or Khul’ before it becomes clear to you as to what is better for you.
Finally, we would like to point out to the two following matters:
Firstly, the guardian should not force his daughter to marry a man whom she does not like, because this married life is a matter of concern to her, whether it is sweet or bitter.
Secondly, childbearing is one of the most important purposes of the Sharee’ah in marriage, and the Sharee’ah encourage having offspring. Nonetheless, the spouses have the right to agree to postpone it for a period of time due to a legitimate interest.
However, neither of them should avoid childbearing without the consent of the other party.
Allah Knows best.
