The tomb of Khwaza Qutab Bakhtiyar Kaki is located in the Mehrauli village, just a kilometer off the Qutab Minar. He is popularly known as Qutab Sahib and had taken the surname 'Kaki'. He is the successor of Khwaza Moinuddin Chisti of Ajmer and is revered for his piety and knowledge. He was born at Ush in modern Iran and visited India in the late 12th century and lived here during the reign of the Slave dynasty. The Dargah is in itself a melting pot for various religions in India and is considered to be a very sacred place by pilgrims of religions. The custom demands every pilgrim who truly believes in the saint to make a wish and tie a thread near the grave. If his wishes get fulfilled, he should return to thank the Khwaza and untie the thread. Thus you will see many colorful threads tied in the marble screens.

Qutab Bakhtiyar Sahib died in the year 1236. His grave is the main shrine of the Dargah. Many emperors have modified the original Dargah in the later years. At present the grave lies in the middle of a rectangular enclosure. This enclosure is paved with marble embellished and surmounted by a dome that was built by the British in 1930s. The western wall is quite attractive as it is decorated with colored floral tiles. This was done on the orders of Emperor Aurangzeb who, though disliked Sufi tradition, revered the saint. The Dargah has many other structures like the assembly house, robe chamber and drum house tanks. To the left of the Dargah is Moti Masjid built by Bahadur Shah I in the year 1709. There are many graves within the premises of this Dargah for there were many who wanted to be buried close to the saint. Among those buried here are the Mughal emperors Bahadur Shah I, Shah Alam II, Akbar II and many persons of royal blood.
