Chishti in the context of "Abu Ishaq Shami"

Mu'in al-Din Hasan Chishti Sijzi (Persian: معین الدین چشتی, romanized: Muʿīn al-Dīn Chishtī; 1 February 1143 – 15 March 1236), known reverentially as Khawaja Gharib Nawaz (Persian: خواجه غریب نواز, romanized: Khawāja Gharīb Nawāz), was a Persian Sayyid Islamic scholar and mystic from Sistan, who eventually ended up settling in the Indian subcontinent in the early 13th-century, where he promulgated the Chishtiyya order of Islamic mysticism. This particular Tariqa (order) became the dominant Islamic spiritual order in medieval India. Most of the Indian Sunni saints are Chishti in their affiliation, including Nizamuddin Awliya (d. 1325) and Amir Khusrow (d. 1325).

Having arrived in the Delhi Sultanate during the reign of the sultan Iltutmish (d. 1236), Muʿīn al-Dīn moved from Delhi to Ajmer shortly thereafter, at which point he became increasingly influenced by the writings of the Sunni Hanbali scholar and mystic ʿAbdallāh Anṣārī (d. 1088), whose work on the lives of the early Islamic saints, the Ṭabāqāt al-ṣūfiyya, may have played a role in shaping Muʿīn al-Dīn's worldview. It was during his time in Ajmer that Muʿīn al-Dīn acquired the reputation of being a charismatic and compassionate spiritual preacher and teacher; and biographical accounts of his life written after his death report that he received the gifts of many "spiritual marvels (karāmāt), such as miraculous travel, clairvoyance, and visions of angels" in these years of his life. Muʿīn al-Dīn seems to have been unanimously regarded as a great saint after his death.
