Dear Mr. Yogesh thanks for reply and showing mirror to every community. In Islam There is no conception of Caste if some one practice it is against the religion In India it is in practice because Hindu brothers since those who converted themself continue to right his caste.But In Islam any person either Mali or Sweeper by caste can read Namaz and even can lead the prayer with out any discrimination can stand one by one in a row .While still SC are not allowed in major temples in South India.Even I have seen Brahmin hate much more to SC than Muslim
