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.
Among the rights of the wife upon her husband is that he provides her with a separate accommodation and she is not obliged to live with any of his relatives as stated by the jurists . For more details, please refer to Fatwa 84608. So, you have the right to ask your husband for this.
Moreover, the husband is obliged to spend on his wife unless she is recalcitrant as clarified in Fatwa 85012. Therefore, if you are not a recalcitrant wife, then you have the right to ask him to spend on you.
As regards work, in principle the wife is not permitted to work without the consent of her husband as we clarified in Fatwa92407. However, if the husband does not spend on his wife and she needs to go out to work, then it is permissible for her to do so even without the consent of her husband. For more benefit, please refer to Fatwa 82399.
On the other hand, it is not at all appropriate to leave the matter like this, i.e. staying separated; reconciliation should be sought as reconciliation is better as Allaah informed us in His Book. Hence, some righteous people from the family of the wife and the family of the husband should be appointed for this purpose. Then, if reconciliation is achieved and the problem is solved by you being provided with a separate accommodation, then this is what is required. However, if you want to be patient with your husband and live with him in the house of his uncle’s wife, then you may do so as well. But if neither of these outcomes is achieved, and it has become impossible to live together, then it might be that divorce is the best solution. Allaah Says (what means): {But if they separate [by divorce], Allaah will enrich each [of them] from His abundance. And ever is Allaah Encompassing and Wise.} [Quran 4:130]
On the other hand, it should be noted here that it is not permissible to accuse someone of anything without evidence, as in principle, a Muslim is innocent [until proven guilty]. Allaah Says (what means): {O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin.} [Quran 49:12] For more benefit, please refer to Fatwa 128834. Instead, a Muslim should endeavor to protect himself by Ruqyah and the authentic Islamic legislated mention of Allaah and Prophetic supplications.
Finally, we ask Allaah to make a way out of your difficulties for you and to facilitate your matter and reconcile between you and your husband as Allaah hears our supplication and He responds to it.
Allaah Knows best.
