Which Sufi teacher was also known as the 'Gharib Nawaz'?

Khwaja Muinuddin

The correct answer is Option (2) - Khwaja Muinuddin

Khwaja Muinuddin was also known as the 'Gharib Nawaz'.

Pilgrimage, called ziyarat, to tombs of sufi saints is prevalent all over the Muslim world. This practice is an occasion for seeking the sufi’s spiritual grace (barakat). For more than seven centuries people of various creeds, classes and social backgrounds have expressed their devotion at the dargahs of the five great Chishti saints. Amongst these, the most revered shrine is that of Khwaja Muinuddin, popularly known as “Gharib Nawaz” (comforter of the poor). The earliest textual references to Khwaja Muinuddin’s dargah date to the fourteenth century. It was evidently popular because of the austerity and piety of its Shaikh, the greatness of his spiritual successors, and the patronage of royal visitors. Muhammad bin Tughlaq (ruled, 1324-51) was the first Sultan to visit the shrine, but the earliest construction to house the tomb was funded in the late fifteenth century by Sultan Ghiyasuddin Khalji of Malwa. Since the shrine was located on the trade route linking Delhi and Gujarat, it attracted a lot of travellers.
