[6] Having arrived in 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.

"[2] Additionally, Muʿīn al-Dīn Chishtī is also notable, according to John Esposito, for having been one of the first major Islamic mystics to formally allow his followers to incorporate the "use of music" in their devotions, liturgies, and hymns to God, which he did in order to make the 'foreign' Arab faith more relatable to the indigenous peoples who had recently entered the religion.

[2] Despite planning to continue his father's business, he developed mystic tendencies in his personal piety[2][clarification needed] and soon entered a life of destitute itineracy.

He enrolled at the seminaries of Bukhara and Samarkand, and (probably) visited the shrines of Muhammad al-Bukhari (d. 870) and Abu Mansur al-Maturidi (d. 944), two widely venerated figures in the Islamic world.

[2]After settling in Ajmer, Muʿīn al-Dīn strove to establish the Chishti order of Sunni mysticism in India; many later biographic accounts relate the numerous miracles wrought by God at the hands of the saint during this period.

The order spread into the Indian subcontinent, however, at the hands of the Persian Muʿīn al-Dīn in the 13th-century,[7] after the saint is believed to have had a dream in which the Islamic prophet Muhammad appeared and told him to be his "representative" or "envoy" in India.

A special National Investigation Agency (NIA) court in Jaipur punished with life imprisonment the two convicts in the 2007 Ajmer Dargah bomb blast case.

[28][29] Various qawwalis portray devotion to the saint including Nusrat Fateh Ali Khan's "Khwaja E Khwajgan", Sabri Brothers' "Khawaja Ki Deewani"and Koji Badayuni's "Kabhi rab se Mila Diya".
