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.
The jurists stated that the wife has the right to be in a separate residence where she will not be harmed by the presence of any of her husband’s relatives; for more benefit, please refer to Fatwa 84608.
Therefore, there is nothing wrong with yours and your husband’s decision to live in a separate accommodation, and this, in itself, is not considered as him being negligent about the rights of his parents, because his obedience to his parents is an obligation in what is permissible only and obeying them in matters that cause harm to his wife is not permissible.
Furthermore, a wife is not obliged to serve her in-laws unless she does so voluntarily and with her proper consent. If she does so, then this is evidence of her kindness and good conduct. For more benefit, please refer to Fatwa 84909.
Kindness should be met with kindness and not with arrogance. Therefore, if your mother-in-law treats you harshly despite all the service that you provide for them at home, then she is wrong. However, it is good that you are patient with her as this is considered as being kind to your husband and avoiding having problems with your mother-in-law as this may lead to bad consequences.
Hence, we advise you to avoid getting into arguments with her, to be gentle with her and to avoid her evil as much as possible. For more benefit, please refer to Fatwa 89154.
Moreover, your mother-in-law has no right to ask her son to divorce you without a sound reason and your husband is not obliged to obey her in this regard. For more benefit, please refer to Fatwa 84056.
As regards the spouses living with the husband's family after marriage, then this is permissible and there is no evidence which prohibits it. If some non-Muslims [like Hindus] are doing it, then this is not evidence that it is prohibited. It might be that they do it based on their pagan rituals. In any case, it is Islamically permissible; rather, some jurists stated that if the husband conditions on his wife to reside with his family, then she has no right to refuse unless she is harmed.
Allaah Knows best.
