Not
far from the Nili-Masjid on its south are the remains of an Idgah, with a
battlemented rubble wall on the west containing a series of eleven mihrabs
and originally terminating on the southern and northern ends in a circular
bastion, the latter now having disappeared. At the rear are three
projections making the position of the 'minhrabs' on the interior.
An inscription on its southern bastion eulogises Iqbal Khan, popularly
known as Mallu Khan, a powerful noble and virtually the ruler during
Mahmud Tughluq's reign. It states that he built the mosque in 807 AH
(1404-05), after the devastation wrought by Timur.
