Whose disciple was Khwaha Moinuddin Chisti ?

Khwaja Moinuddin Chishti received his spiritual training and khilafat from Khwaja Usman Harooni, a pir of the Chishti silsila, at Harun near Nishapur. The Chishti order in India traces its line through Moinuddin, which is why this is the standard fact asked in exams.

Why the other options are wrong:

• Khwaja Abdal Chishti: not Moinuddin's master. The name is only a close-sounding distractor.
• Shah Waliullah: an 18th century Delhi scholar (1703 to 1762) of the Naqshbandi tradition, centuries after Moinuddin, who died at Ajmer in 1236.
• Mir Dard: an 18th century Delhi Sufi and Urdu poet, also of a much later period.

Core concept: the silsila system, where spiritual lineage (pir and murid) defined the authority of a Sufi order. For Mains, this links to the Sufi role in composite culture and the Bhakti-Sufi movement under GS-I.

Trap: aspirants pick the option with a familiar name like Shah Waliullah, forgetting that most of the options belong to much later periods than the Delhi Sultanate.
