Sociological understanding on the issue of caste mostly deals with the classical Hindu caste system or with its present form among Hindus. Due to the fact that Hindu social order is largely based on caste and is written into Hindus texts thus large number of literature on caste revolves around Hinduism. Seeing from this perspective, the existence of caste-like features among non-Hindu, including Muslim, communities in India is generally seen as a result of the cultural influence on these communities of their Hindu neighbours or of Hinduism itself .This paper provide a historical perspective on the issue of caste and caste based discrimination among Muslims and also providing quotations from works which were written in the so called Islamic period of Indian history. It also tried to understand that how Muslim writings, and the Muslim ruling elites more generally, in collaboration with so called upper caste Hindus supported the caste system and the oppression of the so called ‘low’ castes, both Hindu and Muslims.
