Huzoor was elected to the exalted position of the Caliph in 1914. In 1939 he completed twenty-five years of his blessed Caliphate. The honorable Chaudhry Muhammad Zafrulla Khan proposed that on this joyful occasion members should, as a token of gratitude to God Almighty, collect a large sum and present it to Huzoor in a special ceremony. A request should be made to Huzoor to utilize this collection in the service of Islam, or as he deems proper.
Accordingly this epoch-making ceremony took place on the occasion of the Annual Conference of December 1939 and is referred to as Silver Jubilee of the Caliphate. The celebration consisted of speeches by the scholars, a march to the site of the Conference, the illumination of Minaret al-Masih. A cheque in the amount of Rs. 270,000 was presented to Huzoor who stated that the collection would be used on wide-ranging religious projects.
The Liwai Ahmadiyyat (Standard of Ahmadiyyat) was adopted and hoisted for the first time by Huzoor on December 28th, 1939. The flag is black in color, in the middle of the flag is Minaret al-Masih, and on upper two corners are the Crescent and the full Moon in white. The flag is 18 feet long and 9 feet wide.
