Islam is the real revolution that will solve the baffling problems which confront mankind today, more acutely perhaps than ever before in human history. The mission of the Ahmadiyya Muslim Community is to present this solution before the whole world in its proper perspective. This is a translation of a lecture Inqilab-i-Haqiqi at the Annual Gathering of the Ahmadiyya Muslim Community at Qadian on December 28, 1937.
