Chuhra Mela
This was an annual gathering in Qadian, organized by Mirza Imam-ud-Din and composed of the sweeper (chuhra) community from Qadian and adjoining areas, and also claimed to be the re-incarnation of a Hindu-Muslim saint, Lal Beg.
This could be a possible inspiration for Mirza Ghulam Ahmad's Jalsa Salana and for his movement as a whole, as Mirza Imam-ud-Din was a first cousin and rival of Mirza Ghulam Ahmad.
Other parties also confused the two religious movements in Qadian. A reference to this confusion can be found in Malfoozat (Speeches) Vol.5, pp.48-49:
