Advice for a brother-in-law who lives with his sister-in-law and she does not observe hijab in front of him

Question:
A letter sent by the listener, Mr. Amer Muhammad Ismail, from the Arab Republic of Egypt. Our brother has a prolonged issue, the summary of which is that he has a brother living with him, and as he says, he is exposed to his wife, and she does not observe hijab in front of him. So how do you advise him? Especially since he is unable to provide separate housing for himself, his mother, his children, and his wife? What is your guidance? Yes. We summarize what is in his letter? He has a brother living with him in the house, and his wife cannot, she cannot observe hijab in front of him. And he says, I do not know, it is natural. That I provide housing for myself, my children, and my wife. For this brother of mine, how do you advise us? May Allah reward you with good.

Answer:
She can observe hijab in front of him, and he can remain with them in the house, but she must not be alone with him; she must not be alone with her brother-in-law in a place where no one else is present. As for him being with them in the house, with the mother present, and with the other children, she can observe hijab by wearing modest clothing, and she can observe hijab in front of her husband's brother, covering her face and hands in his presence if he is there. And if he goes out, she can uncover her face. What is customary is to uncover what is customarily uncovered. His statement that she cannot observe hijab is incorrect, because observing hijab is easy, and praise be to Allah. She keeps her clothes on her face, head, hands, and the rest of her body in the presence of her husband's brother. If she goes out, she uncovers what is customarily uncovered. May Allah reward you.
