The ruling on a woman uncovering her face in the presence of her husband's brothers and conversing with them

Question:
May Allah reward you. A message was received from Abu Suqar from Yemen. He says: Honorable Shaykh, is it permissible for a woman to uncover her face and converse with her husband's brothers?

Answer:
It is not permissible for a woman to uncover her face in the presence of her husband's relatives, such as his brothers and others; because they are strangers to her, they are not mahram. She must cover her face and cover her body from them. There is no harm in her sitting with them in a secluded place where there is no free mixing, and conversing with them while wearing the hijab; because this does not involve seclusion and there is no harm in it, but with the hijab. And Allah (Exalted and Majestic is He) says to the Companions regarding the wives of the Prophet (peace and blessings be upon him), who were the purest community on the face of the earth, So He made the hijab a means of purifying the hearts, and purity is required of every Muslim always and forever. If this address was for the Companions and the wives of the Prophet (peace and blessings be upon him), who were the purest and most noble people on earth, what about others? Yes.
