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.
If a wife is harmed by her husband, then she has the right to ask him for a divorce; please refer to fatwa 84309.
If she hates him and fears to be negligent about his right, then she has the right to ask him for a khul’ in return for compensation; please refer to fataawa 86307 and 297616.
We advice you to supplicate Allaah to rectify your affairs and have rational and wise people would interfere for this purpose. In case this is of no avail and marital life becomes impossible, then the benefit of divorce becomes more preponderant.
Your parents – let alone other people – have no right to force you to stay with your husband in those conditions. Obedience to the parents is only required in what is permissible, as is confirmed by the Sunnah. Indeed, it is neither permissible nor reasonable for the parents to order their daughter to do something that harms her. For the limits of obedience to parents, please refer to fatwa 84942.
If it is not possible to convince your husband to agree to divorce you or give you a khul’, then you may take the matter to the nearest Islamic center to you in order for them to study your case and remove harm from you either by a divorce or a khul’.
We did not understand what you mean by the statement of that imaam, that you can only get a divorce if your husband releases you during your 'iddah period.
Finally, we should also point out that the wife should respond to her husband if he invites her to bed and that she is not permitted to refuse without a valid excuse. If the husband is unjust to his wife, then some scholars are of the view that she is permitted to desert him in bed. Ibn Hajar said, "...she is not to be blamed unless she began deserting him, and he became angry because of this, or that he deserted her while she is unjust and she did not seek pardon for her sin and deserted him, but if he started deserting her while he is unjust to her, then she is not to be blamed.”
It is not permissible for the wife to imagine having intercourse with somebody else other than her husband in order to satisfy her sexual desire. Please, refer to fatwa 87197.
Allaah knows best.
