Hazrat Mirza Bashir-ud-Din Mahmud Ahmad(ra) (1889-1965), the Musleh Mau‘ud (the Promised Reformer), was the son of the Promised Messiah(as) and his second successor. He was elected as the khalifa of the Ahmadiyya Muslim Community in 1914 at the age of 25 and led the movement for 52 years. In the period of his khilafat, the message of Ahmadiyyat spread to countries as far and wide as the United States of America and Japan. He also set the foundations of the community’s administrative structure and launched numerous initiatives for the propagation of Islam, most notably Tehrik-e-Jadid and Waqf-e-Jadid. A prolific writer, orator and the author of a ten-volume commentary of the Holy Qur’an, he leaves a profound and enduring legacy which lasts to the present day.
