At the end of the booklet, the Promised Messiah(may peace be on him) announces his acceptance of a mubahalah (prayer duel) challenge issued by Abdul-Haqq Ghaznavi. The Promised Messiah(may peace be on him) also lists the names of twenty other ulema whom he invites to come forward against him and either accept the mubahalah challenge or acknowledge defeat through their silence and failure to respond. This mubahalah took place at the Eid Gah in Amritsar after the Jang-e-Mugaddas debate was conducted at the residence of Dr Henry Martyn Clarke.
Hazrat Mirza Ghulam Ahmad (1835-1908), the holy founder of the world-wide Ahmadiyya Muslim Community, born in Qadian, a village in rural Punjab, India, was the Divinely appointed Reformer of the latter days and the Promised Messiah and Mahdi. He was sent by God in fulfilment of the prophecies contained in the Holy Bible, the Holy Quran and Hadith, with the express task of rediscovering Islam in its pristine purity and beauty, and bringing mankind back to the Creator.
