<P> The central mihrab in the mosque contains an inscription indicating the completion date of the mosque . It is dated Jumada II 595 AH (April 1199 CE). This makes the mosque one of the oldest in India, and the second mosque to be built by the Mamluks of Delhi (the first being the Quwwat - ul - Islam mosque). Another inscription, dated Dhu al - Hijjah 596 AH (September--October 1200 CE), names Abu Bakr ibn Ahmed Khalu Al - Hirawi as the supervisor of construction . This makes Adhai Din Ka Jhonpra one of the oldest mosques in India, and the oldest surviving monument in Ajmer . </P> <P> Iltutmish, the successor of Qutb - ud - Din - Aibak, subsequently beautified the mosque in 1213 CE, with a screen wall pierced by corbelled engrailed arches--a first in India . An inscription on the central arch of the screen as well as two inscriptions of the northern minaret contain his name . The second arch from the south names one Ahmed ibn Muhammad al - Arid as the construction supervisor . </P> <P> The mosque seems to have been ignored by the later kings . It does not find a mention in Taj - ul - Maasir, the earliest history of the Mamluk dynasty . It is not mentioned in Khalji, Lodi, Rathore, Sisodia and Mughal chronicles either . The Maratha leader Daulat Rao Sindhia (1779--1827) restored the central dome of the building, and imposed a ban of removal of stones from the structure . An inscription dated Saavan 1866 VS (1809 CE) exhorts Hindus and Muslims not to remove stones from the ancient building . </P> <P> In 1818, Ajmer came under the Company rule . James Tod visited the mosque in 1819, and described it in his Annals and Antiquities of Rajastʼhan as "one of the most perfect as well as the most ancient monuments of Hindu architecture ." Subsequently, Alexander Cunningham, the Director - General of the Archaeological Survey of India (ASI) inspected the building in 1864, and described it in the ASI report of that year . Tod believed the earlier structure to be a Jain temple . However, Cunningham pointed out that this could not be correct, since the pillars in the building feature several four - armed figures (characteristic of Hindu gods) besides a figure of the Hindu goddess Kali . </P>
