The ruling on a man standing in the same row as a woman in prayer

Question : May Allah reward you. If a man prays with his wife in a row by themselves, does the row count as valid with just the two of them? And is the prayer valid?

Answer : A man and a woman cannot stand together in the same row, never, even if a man leads his wife in prayer at home, he stands in front of her and she is behind him, because there is no place for a woman in a row of men, never. In fact, the Prophet (peace and blessings be upon him) said: because the last row is the farthest from the men. But sometimes there is a dire necessity, especially in the Sacred Mosque and the Prophet’s Mosque. In that case, women may be in a row with men; there is nothing wrong with that due to dire necessity. Or a row of women may be in front of men; there is nothing wrong with that due to dire necessity. But if a person knows from himself that he cannot bear this.
