Hazrat Abdullah bin Ubaidullah bin Abi Mulaykah narrates that my father, Hazrat Ubaid bin Umair, Hazrat Miswar bin Makhramah, and many other people used to visit Hazrat Aisha (may Allah be pleased with her). Hazrat Aisha’s (may Allah be pleased with her) freed slave, Abu Amr, used to lead them in prayer. At that time, Abu Amr was still a slave and had not yet been freed.
