Chapter: The waiting of the people for the religious learned Imam to get up (after the prayer to depart)
Narrated `Aisha:
Had Allah's Messenger (ﷺ) known what the women were doing, he would have forbidden them from going to the mosque as the women of Bani Israel had been forbidden. Yahya bin Sa`id (a sub-narrator) asked `Amra (another sub-narrator), "Were the women of Bani Israel forbidden?" She replied "Yes."
