Explanation:

The Qutb complex are monuments and buildings from the Delhi Sultanate at Mehrauli in Delhi in India. Construction of the Qutub Minar "victory tower" in the complex, named after the religious figure Sufi Saint Khwaja Qutbuddin Bakhtiar Kaki, was begun by Qutub-ud-din-Aibak, who later became the first Sultan of Delhi of the Mamluk dynsty (Gulam Vansh). It was continued by his successor Iltutmish (a.k.a. Altamash), and finally completed much later by Firoz Shah Tughlaq a Sultan of Delhi from the Tughlaq dynasty(1320-1412) in 1368 AD. The Qubbat-ul-Islam Mosque (Dome of Islam), later corrupted into Quwwat-ul Islam, stands next to the Qutb Minar.
