In this short and incisive tract, Hazrat Mirza Ghulam Ahmad(as) responds to the contention made by Hafiz Muhammad Yusuf that even false claimants of Prophethood can establish successful missions. Through the use of this critique Muhammad Yusuf hoped to undermine the success of the Promised Messiah(as). With strong, reasoned arguments Hazrat Mirza Ghulam Ahmad(as) deconstructs this thesis and exposes its inherent flaws and defects.
