What is the ruling on a husband's insistence that his unmarried sister reside in their private home during their absence, despite the wife's refusal and the violation of her privacy?

Couples are advised to be understanding and cooperative for a stable marriage, as Allah Almighty says: "And among His Signs is this, that He created for you mates from among yourselves, that you may dwell in tranquility with them, and He put love and mercy between you. Verily in that are Signs for those who reflect."

If the house is owned by the husband, he has the right to accommodate his sister in it, provided that she is not allowed to enter the wife's bedroom. This does not contradict the wife's right to an independent dwelling as long as the wife has left the house.

It is important to note the danger of a wife staying alone in the house, as the Prophet (peace be upon him) forbade solitude, and this is especially true for women due to their vulnerability.

The husband must provide the obligatory financial support for his wife and child and be generous to them without extravagance. After that, he may give charity to his family. The wife should be a helper to him in this, and it is desirable for her to advise him to save money, as the Prophet (peace be upon him) said: "It is better for you to leave your heirs wealthy than to leave them dependent, begging from people."
