The working committee of the MAI, in a meeting at Lahore on 12 June 1933, took the decision to participate in the three by-elections for the Punjab Assembly. It selected three prominent MAI figures as its candidates to contest these polls ,one of whom was Chaudhry Abdul Rahman Khan. He was selected to contest the Muslim urban seat from the Sheikhupura, Ludhiana, Gurdaspur and Jullunder’s area.
He led the Ahrar agitation in Kapurthala. The movement for the rights of the poor Muslims in Kapurthala State raised its profile and popularity even further. The vast majority of Muslims were peasants, living in abject misery. Sixty percent of the state revenue accrued through the taxes paid by Muslim peasants. More over the Hindu moneylenders subjected the poor peasantry of Begowal and Bholeth areas of the state to the merciless economic exploitation. So the situation was ripe for Ahrar to intervene immediately after their Kashmir campaign which had won Ahrar tremendous accolade as champion of the Muslims.
