My father says that: when a woman offers obligatory Salah, it is impermissible to pass in front of her.
Please inform us on this, may Allah reward you.A:
Putting a Sutrah (barrier placed in front of a person praying) is a necessity for both men and women. It is impermissible for anyone to pass in front of a person offering Salah, or between them and their Sutrah, whether the person praying is a man or a woman, and whether the passing person is a man or woman. But, if the passing person is a woman, her passage would interrupt the Salah of the person she passes in front of, or between them and their Sutrah, except in
Al-Masjid Al-Haram (the Sacred Mosque in Makkah) where she would be excused for the difficulty of preventing that from taking place. Allah (Glorified and Exalted be He) says:
So keep your duty to All?h and fear Him as much as you can
...and He has not laid upon you in religion any hardship
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
