Hazrat Moinuddin Chishti was a 13th-century Sufi saint and philosopher. Born in Sanjar (of modern-day Iran), or in Sijistan, he arrived in Delhi during the reign of the Sultan Iltutmish (d. 1236). Moinuddin moved from Delhi to Ajmer shortly thereafter, at which point he became increasingly influenced by the writings of the famous Sunni Hanbali scholar and mystic ʿAbdallah Ansari.
