In Indian sufism anti-Hindu polemics began with Muin al-din Chishti. Early Sufis in the Punjab and early Chishtis devoted themselves to the task of conversion on a large scale. Missionary activity slowed down under Nizam al-din Auliya, not because of any new concept of eclecticism, but because he held that the Hindus were generally excluded from grace and could not be easily converted to Islam unless they had the opportunity to be in the company of the Muslim saints for considerable time.
