Fig. 85: FATEHPUR MASJID AND CHANDNI CHOWK, studio of Mazhar Ali Khan, c. 1840. From Metcalfe's Delhi Book. The Fatehpuri Masjid was built in 1650 at the end of the Chandni Chowk thoroughfare by one of Shahjahan's queens Fatehpuri Begum. Fatehpuri Masjid was built in 1650 by Fatehpuri Begum, one of emperor Shah Jahan's wives who was from Fatehpur Sikri,[1] and the mosque at Taj Mahal is also named after her.[2] The British had auctioned the mosque after the 1857 war to Rai Lala Chunnamal for Rs. 19,000[3](whose descendants still live in the Chunnamal haveli in Chandni Chowk[4]), who preserved the mosque. Later in 1877 it was acquired by the government in exchange for four villages and was restored to the Muslims at the Delhi Durbar when the British allowed the Muslims back in Old Delhi. A similar mosque, called Akbarabadi Mosque built by the Akbarabadi Begum was destroyed by the British.[5] The Khari Baoli, which is today Asia's largest spice market, gradually developed after the construction of the mosque. Muslim festivals Id-ul-Fitr and Id-ul-Zuha are celebrated with great enthusiasm at the mosque. Mufti Mukarram Ahmad is the chief mufti and imam of the mosque and has been Imam there for almost 42 years and before him his father Maulana Mufti Mohammad Ahmad (d. 21 October 1971/1391 AH) was imam and mufti of the mosque.
