Caste system among South Asian Muslims

Muslim communities in South Asia have a system of social stratification arising from concepts other than "pure" and "impure", which are integral to the caste system in India. It developed as a result of relations among foreign conquerors, local upper-caste Hindus convert to Islam (ashraf, also known as tabqa-i ashrafiyya) and local lower-caste converts (ajlaf), as well as the continuation of the Indian caste system by converts. Non-ashrafs are backward-caste converts. The concept of "pasmanda" includes ajlaf and arzal Muslims; ajlaf status is defined by descent from converts to Islam and by pesha (profession). These terms are not part of the sociological vocabulary in regions such as Kashmir and Uttar Pradesh, and say little about the functioning of Muslim society.

The Biradari system is social stratification in Pakistan and, to an extent, India. The South Asian Muslim caste system includes hierarchical classifications of khandan (dynasty, family, or lineage).
