In a public gathering in Delhi in 1944, he made the claimed that he was the ‘Promised Son’ whom his father Mirza Ghulam Ahmad had foretold would be born within 9 years. He explained in a number of meetings held in various places in India that this claim was based on revelations and dreams. He clarified that he wasn't the only Promised Son, and other 'Promised Sons' would appear in accordance with prophecies, some even after centuries. He also prophecied that he would, as it were, return in the form of another Promised Son for the reform of the world at a time when shirrk (polytheism) would have become widespread. Some of the prophecies about the Promised Son are yet to be fulfilled.
He also managed the translation and publication of the Qur´an into various languages. His ten-volume “Tafseer-e-Kabeer” is one of the most detailed commentaries done on the Qur´an in modern times. His scholarship of religious and secular subjects was well known among the literary circles. He delivered a series of famous lectures on a variety of topics in educational institutions which were attended by the intellectuals and leaders of that time.
