The only exception is the Haram of Makkah as Sheikh Ibn Bazza said due to the difficulty of praying to a screen.

In response to your answer to a previous question by a Brother (ref#4036), you mentioned about a woman crossing a man and thus nullifying his salahHowever, when we see people in Makkah circumambulating around the Ka’bah as well as moving around there, many a time women cross other men reading salah there. Does it nullify the salah for the man as well? Its really difficult isnt it in these situations, what should one do then?
