The ruling on a woman sitting with a blind man in the presence of women

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: Is it permissible for my wife to sit with my blind brother in the presence of women for a long time, and she may exchange words with him, and there may be a verbal dispute between them? Is this action permissible?

Answer:
If there is no seclusion between them, and women are present, and you are present, and there are others whose presence removes the seclusion, then there is no harm. What is forbidden is seclusion. If there is someone present whose presence removes the seclusion in the place, then there is nothing wrong with it. If he is sighted, she must observe hijab from him. As for the blind man, the correct view is that she is not required to observe hijab from him.
