"Muslim ‘community’ in India had remained sharply divided into two mutually exclusive segments throughout the centuries of Islamic invasions and rule over large parts of the country. On the one hand, there were the descendants of conquerors who came from outside or who identified themselves completely with the conquerors - the Arabs, the Turks, the Iranians, and the Afghans. They glorified themselves as the Ashrãf (high-born, noble) or Ahli-i-Daulat (ruling race) and Ahl-i-Sa‘adat (custodians of religion). On the other hand, there were converts from among the helpless Hindus who were looked down upon by the Ashrãf and described as the Ajlãf (low-born, ignoble) and Arzãl (mean, despicable) depending upon the Hindu castes from which the converts came. The converts were treated as Ahl-i-Murãd (servile people) who were expected to obey the Ahl-i-Daulat and Ahl-i-Sa‘adat abjectly. Shah Waliullah (1703-62) and his son Abdul Aziz (1746-1822) were the first to notice this situation and felt frightened that the comparatively small class of the Ashrãf was most likely to be drowned in the surrounding sea of Hindu Kafirs. ... They had to turn to the neo-Muslims. The neo-Muslims, however, had little interest in waging wars for Islam. They had, therefore, to be fully Islamized, that is, alienated completely from their ancestral society and culture. That is why the Tabligh movement was started."
