The ruling on a woman covering herself from her husband's brothers

Question:
And may Allah bless you. We move on to the letter from the brother questioner A. A. J. He says: Shaykh, I am from an Arab country, and my wife does not cover herself from my brothers, who are older, and she refuses to do so. What is the ruling on her action? May you be rewarded.

Answer:
It is obligatory for her to cover herself from your brothers because they are non-mahram to her. The Prophet (peace and blessings be upon him) was asked when he said, "Beware of entering upon women." They said, "O Messenger of Allah, what about the in-laws, i.e., the relatives of the husband?" Because he needs to enter and to... He said, "The in-law is death," because his danger is more severe. It is obligatory for a woman to cover herself from her husband's brother, his paternal uncle, her maternal uncle, and his relatives, except for her husband's father, for she does not cover herself from him because he is a mahram to her, or his grandfather. And except for her husband's son from another woman, or his son's son, for he is a mahram to her.
