From 1896 to 1914 the plague ravaged British India, and more particularly, the province of Punjab. During these perilous times, as towns and cities were devoured, the British government undertook efforts to save the people from this pandemic through inoculation. It was in this backdrop that MirzaGhulam Ahmad of Qadian penned Noah's Ark in 1902. In it the author elaborates the essence of his teachings and states that those who sincerely follow its tenets would be saved miraculously from the onslaughts of this epidemic, even without inoculation. This was a prophecy vouchsafed to him by God. History testifies to the magnificent fulfilment of this prophecy. The book Noah's Ark shines as a beacon of hope not only for the people of the past, but also now and shall continue to grant salvation to the world in all ages. It is a book that stands as one of the most influential works of the Promised Messiah and Mahdi, and continues to transform lives even today.
