All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
We ask Allah, The Almighty, to facilitate your affairs and relieve your distress. We advise you first of all to supplicate Allah frequently to fulfill your needs and relieve you of your distress and to remember Him as much as you can with Thikr (expressions of remembrance of Allah); indeed, the remembrance of Allah is a source of solace and peace of mind; it relieves anxiety and depression. Allah, The Exalted, says (what means): {Those who believed and their hearts are assured with the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured.} [Quran 13:28]
It is your right as a wife to live in a separate house, independent from your in-laws. You are not obliged to live with them, as has been underlined by scholars of Fiqh; please refer to fatwas 84608 and 86388. The same applies to serving your husband's family; you are not obliged to serve them, as we have previously underlined in fatwa 84909.
Islam commands the husband to be kind and compassionate towards his wife. Allah, The Exalted, says (what means): {And live with them in kindness...} [Quran 4:19]
It is not kindness that the husband yells at his wife when she asks him for her legitimate right. It is also not kindness that he does not take into account your condition of weakness and pregnancy. This necessitates that you do less work and receive help in housework, not that he makes the burden heavier for you.
There is no doubt that your situation requires wisdom in treating it so that you receive your legitimate rights. You should also not hasten to ask for divorce; it is not always the solution. Rather, you should be patient and discuss the matter with your husband gently. You may seek the mediation of someone whom you believe your husband would listen to, whether a relative or otherwise. There is no harm in seeking the help of such a person to talk to your husband in this regard.
As for your husband's kindness towards his family and helping them financially, this is commendable of him. However, it is impermissible for him to do so at the expense of his wife and children while neglecting their rights over him as a result.
Allah knows best.
