Did Prophet Expel Hypocrites From The Mosque??
I am unaware of such thing. No one was aware who was munafiq. It is rported that Abd-Allah ibn Ubayy who was known for his enimity towards Islam when died prophet Mohahmaad saw prayed for him https://sunnah.com/nasai:2020 Prophets are helped by Allah they can know who is on straight path who is not. Even if he did it, it would have with the advise of God. Ask them for references. I am sure they will be not authentic. Only event I know is of MAsjid e zarar which was demolished by the order of Prophet Mohammad saw. A common person has no idea who is on right path and who is not.
