In the records of Kerala, the role of religious conversion in the growth of Muslims in Malabar cannot be omitted. Religious conversion is the adoption of a set of ideals identified with a particular nonsecular denomination to the exclusion of others. An inflexible caste system in Malabar gave remarkable growth to Islam. Like Christianity, Islam is a missionary faith, but pressured conversion is not practiced by using Islam like different missionaries. Conversion to Islam becomes a method found by the lower castes to get away from persecution from the top castes.
