In 1890 God Almighty revealed to him that Hazrat Isa ibn Maryam(as) had passed away like all previous prophets. The belief that he is alive in the heavens, is false and against the teachings of the Holy Quran. Also he proclaimed that the Messiah whose advent was foretold by Holy Prophet Muhammad, peace & blessings of Allah be on him, has appeared in his person. God has sent this Promised Messiah to reform the world and to spread the pristine teachings of Islam.
His announcement and claim to be the Promised Mahdi and the Messiah brought him numerous converts, but there were some that turned against him. Erstwhile friends became his foes. Some Muslim divines declared him a heretic. The Christians did not lag behind either as they raised a fierce storm of opposition. The reason Christians opposed him was the fact that Jesus Christ’s death dealt a fatal blow to the very foundation of Christianity. They believed Christ to be their Lord, but this claim made him a dead god.
This intense opposition resulted in many debates between him, the Muslim divines, and the Christian missionaries. For instance in 1891 he held debates with Maulvi Muhammad Hussain sahib Batalvi, Maulvi Sayyed Nazeer Hussain sahib Dehlvi and Maulvi Muhammad Bashir sahib Bhopali. In 1892 he held debates with Maulvi Abdul Hakim Kalanauri. In 1893 he held a famous debate with Christian missionary Abdulla Athim. These debates brought him many pious & devoted converts.
