Qutb Sahib Bakhtiyar Kaki was a 14th century saint of the Chishti order. His dargh, or shrine, was a popular place of pilgrimage even during his life. Babur visited this shrine in his visit to Delhi in 1526. Later Mughal emperors, starting with Shah 'Alam Bahadur Shah (r. 1707-), patronized the shrine and the followers of Bakhtiyar Kaki, a relationship that the rulers valued as an association with moral and religious authority. The tomb of Shah 'Alam Bahadur Shah was built adjacent to the shrine, near the Moti Mosque which he commissioned. Farrukh Siyar (r.1713-19), the next emperor, continued patronizing the shrine, adding a screened marble enclosure and two marble gates. Under Muhammad Shah (r.1719-48), the link between the shrine and the rulers was celebrated by the installation of elaborate lighting devices that lined the road leading from the palace in Shahjahanabad to the shrine, 15km away.
