It was called Bani Muaweya Mosque but now its called Ijaba, answering, mosque. It is located at the north side of Al Baqi'. Imam ahmad recorded that Sa'd bin Abi Waqqas said: we accompanied the Messenger of Allahand passed by Bani Muaweya Mosque. The prophet went n and offered a two Raka'h prayer, and we prayed behind him. He supplicated to his lord for a long time and then he said , ( I asked my Lord for three: I asked him not to destroy my Ummah (Muslims) by drowning and he gave that to me. I asked not to destroy my Ummah by Famine and he gave that to me. And I asked him not to make them taste the violence of one another, but he did not give that to me" Sahih Muslim.
