"The two greatest Chishti Mashaikh of the medieval period were Muin-ud-din Chishti and Nizam-ud-din Auliya. Rizvi rightly says that Shaikh Muin-ud-din Chishti “was neither a missionary nor a miracle monger. He did not work among the masses…” In the Fawaid-ul-Fuad, a biographical memoir on Shaikh Nizam-ud-din Auliya, there is mention of conversion of only two Hindu curd-sellers. Similarly during the reign of Iltutmish, Khwaja Qutubuddin Bakhtiyar Kaki and Qazi Hamid-ud-din Nagori were two prominent saints in Delhi but no proselytizing activity is attributed to them."
