Nishan-e-Asmani (The Heavenly Sign or the testimony of the recipients of revelation) first published in 1892, is one of the smaller but equally important books by Hadrat Mirza Ghulam Ahmad of Qadian (1835-1908), the Promised Messiah and Mahdi (peace be upon him).
It is a closely reasoned thesis, primarily based on prophecies made by some earlier Muslim saints and seers about the Coming of the Promised Messiah and Mahdi. That all the events precedent to the Coming happened as prophesied and that they conclusively established the claim of the revered author to be the Promised Messiah and Mahdi, is part of history. He has since been globally hailed and accepted by tens of millions of devoted followers - the Ahmadiyya Jama'at, known for their genuine commitment to religious values, devotion to the Living God, service to the mankind, piety and peaceful communication of the Truth.
