Not of much interest structurally, the Masjid-i-Usmani is of much historical importance. It is the first mosque in Chanderi which has the building and inscription both intact. It is the earliest among all extant mosques based upon the inscription found installed. Located in the Sadar Bazaar area of the town, the mosque has been dated to the reign of the Delhi Sultan Mohammad Shah Tughlaq son of Firoz Shah.
The inscription, written in Persian, in Naskh letters consists of eight verses arranged in four lines. It records the date of construction of the mosque as AH 795 or AD 1392 and describes Dilawar Khan, the then Chanderi Governor as a favoured courtier.
Another inscription recovered from the home of a Chanderi resident informs of the raising of a mosque in the reign of Alauddin Muhammad Khilji of Delhi in 1312. Although the mosque has not survived, its inscription presents the earliest written evidence towards the construction of a mosque in Chanderi.
The inscription, written in Persian, in the Suls script, consists of the four following lines:
This mosque was constructed in the reign of the kingdom of the magnificent Sultan Alaud-Dunya wal-Din, Iskander of the age, Abul-Muzaffar Muhammad Shah,
The Sultan, may Allah perpetuate his kingdom and sovereignty, and further his affairs and position, and in the time of the niyabat of Amir-ul-Umara
The refuge of the great, Ikhtiyarud-Daulat wal-Din, the champion of Iran, Tamur Sultani, may Allah perpetuate his glories and increase his fortune!
The being, hopeful of mercy in the House of Peace, Ismail, son of Abdus-Salam, called Wajih-i-Najib, the muharrir attached to the district of Kol, completed it on the twentieth of the month of Shaban, year eleven and seven hundred.
