Performing Salaah in jamaat with a na-mahram man
Q: I wanted to know a couple of things concerning the validation of prayer. If a man and a woman are in a haraam relationship (adultery), can he lead her in prayer alone? If a women is at a female friends house can she pray with her friends husband and son? If a women comes into the mosque and there are no other females and only one male there already praying should she follow behind him in prayer?
