The existence of caste system or reservation for Muslim dalits/backward classes has always been a controversial issue. SC/ST status demand for Muslims not accepted so far. However there are classification for OBC Muslims separately in each state.
In some states like Kerala and Andhra separate reservations to Muslims are available.
It is an undisputed fact that though there is no caste system in Islam, Indian Muslims did develop a hierarchical structure by recognizing numerous biradaris. Some Muslims established superior status for themselves as ashraf or noble on the basis of their foreign descent, while some indigenous converts are commonly referred to as ajlaf or ‘lowly’.
