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.
As a wife, you have the right to have a separate accommodation instead of living with your in-laws. Your husband is obliged to provide you with a separate accommodation even if it is leased. Please refer to Fatwa 84608.
You should discuss this matter with your husband and explain to him that living in a separate accommodation is one of the most important means for preserving and maintaining the stability of the family.
Your husband should be understanding and should not impose such a harsh life on you given the potential undesirable results. You may also seek help from wise people in your family or his family in order to solve the problem.
Your husband should live with you in kindness and should not allow anyone to ruin the relationship between you. If he hears something bad about you, he should investigate and verify it first; Allaah, The Exalted, says (what means): {O you who have believed, if there comes to you a disobedient one with information, investigate, lest you harm a people out of ignorance and become, over what you have done, regretful.}[Quran 49:6]
Dear sister, remind your husband that he should not disclose to anyone the details of your private life and whatever you do whether inside or outside the house; doing that may bring about envy. There are authentic Hadeeth reports that advise Muslims to conceal their personal affairs as a means to shield themselves against envy. Mu‘aath ibn Jabal narrated that the Prophet said: “Resort to secrecy for the fulfillment and success of your needs, for every one favored with a blessing is envied.” [At-Tabaraani - Al-Albaani graded it Saheeh (sound)]
On the other hand, Muslims are enjoined to be affectionate to each other and not to desert each other. It is impermissible for a Muslim to desert his fellow Muslim for more than three nights except for a reason a legitimate reason. Abu Ayyoob Al-Ansaari narrated that the Prophet said: “It is impermissible for a man to desert (keep apart and stop talking to) his Muslim brother for more than three nights. (It is unlawful for them that) when they meet, each of them turns his face away from the other; and the better of the two is the one who greets the other first.” [Al-Bukhari and Muslim]
Allaah Knows best.
