In the early Twenties the Arya Samāj (a Hindu reformist Movement) started the Shuddhi missionary campaign to revert to Hinduism, those who had converted to other faiths (in most cases to Islam), particularly the Malkanas, a group of Rajputs. The Shuddhi Campaign had been somewhat successful in their activity between 1922-1923[13] and had been active in Agra and in the Punjab. When Mahmood Ahmad came to know of this activity he launched a counter campaign by setting up a network of missionaries across Uttar Pradesh where this activity was rife, to propagate the teachings of Islam and save people from converting to Hinduism.[14]
In 1923, he sent a delegation of Ahmadis to the area to prevent the advancement of the Shuddhis, an act which earned him some popularity among the Muslim elite of India. After having faced extreme resistance, the Aryas announced the end of the Shuddhi movement in September 1923,[15] Though later, the president of Bhartiya Hindu Shuddhi Sabha, Swami Shraddhanand was stabbed by a Muslim fanatic, Abdul Rasheed in 1926. In the latter part of the Twenties and early Thirties, under Mahmood Ahmad’s directives various gatherings and meetings were held across the Indian subcontinent commemorating the life of the Islamic Prophet Muhammad known as (Jalsa Seeratun-Nabi) attended by Mulsims and non-Muslims alike. A practice which is still carried out by Ahmadis today.[16]
