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 slave and messenger.
First of all, you should know that your wife has the right to a separate accommodation, and she is not obliged to dwell with your parents. Hence, if she left the house and refused to return because of being uncomfortable with living with your family, then she is not considered Naashiz (recalcitrant/rebellious). However, if she does not have a legitimate excuse, then she is Naashiz. For more information, please refer to Fataawa 84608 and 99860.
Also, a Naashiz wife has no right to financial support from her husband as we have explained in Fatwa 196333.
As regards her rights as a divorced woman, such as her right to the delayed dowry and the like, then she does not lose those rights by being Naashiz. But if it was agreed that the husband would divorce her in return for compensation, then she is obliged to give such compensation, such as giving back the dowry or renouncing it or renouncing the delayed dowry, and the like.
For more information on the rights of a divorced woman after divorce, please refer to Fataawa 86603 and 89039 on explaining the rulings pertaining to Khul’.
We should point out that both parents have the right to see the child when he/she is under the custody of both of them when the bond of marriage is still valid, or when the custody only belongs to one of the parents in case of separation [divorce]; we have clarified this in Fatwa 99860 to which we have referred you above.
Finally, we recommend that you reconcile if possible; Allaah says (what means): {And if you fear dissension between the two, send an arbitrator from his people and an arbitrator from her people. If they both desire reconciliation, Allaah will cause it between them. Indeed, Allaah is ever Knowing and Acquainted [with all things]}. [Quran 4:35]
Allaah also says (what means): {And if a woman fears from her husband contempt or evasion, there is no sin upon them if they make terms of settlement between them - and settlement is best. And present in [human] souls is stinginess. But if you do good and fear Allaah - then indeed Allaah is ever, with what you do, Acquainted.} [Quran 4:128]
So, you should not resort to divorce or Khul’ unless a greater interest is involved.
Allaah Knows best.
