The mosque known as Quwwatu'l-Islam Masjid is located
adjacent to Qutub Minar in Delhi. It is believed to have been built
using the carved stone slabs and materials of the remains of Hindu
Temples. Delicate brocade designs and Islamic inscription adorn this
structure. Its pillars have clear Hindu motifs and are believed to have
been taken from the 27 temples of Qila Rai Pithora, the city of the
Rajput King Prithviraj Chauhan. In the inscriptions belonging to the
times of Qutub-ud-Din, this mosque is mentioned by the name of Jami
Masjid or Friday Mosque. Built by Qutub-ud-din Aibak, it was completed
in four years.
