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, sallallaahu ‘alayhi wa sallam, is His alave and messenger.
We implore Allaah to relieve your distress, ease your hardship, and bless you and your husband with happiness. You are advised to turn to Allaah in supplication regarding all your affairs. Verily, Allaah is the best one to be asked and the best one to answer the supplications. Allaah, The Exalted, says (what means): {And when My servants ask you, [O Muhammad], concerning Me - indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided.} [Quran 2:186]
One of the due marital rights that both spouses should fulfill is to live with each other in kindness. Allaah, The Exalted, says (what means): {…And due to the wives is similar to what is expected of them, according to what is reasonable. But the men have a degree over them [in responsibility and authority]. And Allaah is Exalted in Might and Wise.}[Quran 2:228]
If both spouses carry out their duties and fulfill the rights of one another, they will relish marital stability and savour happiness and accordingly their children will have a sound and healthy upbringing. This should be known to all spouses. For more information, please refer to Fataawa 85167 and 85308 about the rights and duties of both spouses.
On the other hand, if the wife did not stipulate in the marriage contract that her husband should not take her out of her town, she is obliged to live with her husband in whatever place he is residing and it is impermissible for her to refuse to move to another place with him for no valid (and Sharee‘ah-acceptable) excuse. For instance, she is allowed not to move with him if the place is not safe. If your husband asks you to travel with him and provides you a separate place of residence, independent from the dwelling of his family, you should travel with him. It is incumbent on your husband to spare you any trouble his family may cause to you. For further information, please refer to Fatwa 224677.
It should be noted that it is better to reach a mutual understanding and reconciliation, whenever possible, whether it is regarding your place of residence, your husband's care for you and your children, or anything else that you may encounter in your marriage. Once more, we emphasize that you should take into account the interest of your children as well as their psychological wellness.
Allaah Knows best.
