Hazrat Nasiruddin Mahmud Chirag-e-Delhi (ca 1274-1356) was a 14th century mystic-poet and a Sufi Saint of Chishti Order. He was a murid (disciple) of noted Sufi saint, Hazrat Nizamuddin Auliya, and later khalifa, his successor.

He was given the title, “Roshan Chirag-e-Delhi”, which in Urdu, means “Illuminated Lamp of Delhi”.

Hazrat Nasir Uddin Mahmud Chiragh Dehlavi (or… Chiragh-e-Delhi) was born as Nasiruddin around 1274, at Ayodhya, Uttar Pradesh. His father Syed Yahya, who traded in Pashmina, and his grand father, Syed Abdul Latif, first migrated from Khorasan, north-eastern Iran, to Lahore, and thereafter settled in Ayodhya, in Awadh. His father died when he was only nine years of age, thereafter growing up with his mother, he received his early education from Maulana Abdul Karim Sherwani, and later continued it, with Maulana Iftikhar Uddin Gilani.

At age forty, he left Ayodhya for Delhi, where he became the disciple of Khwaja Nizamuddin Auliya, it was here that he stayed for the rest of his life as his murid (disciple),and eventually after his death, became his successor. In time, he also became a known poet in Persian language.

He died in 18 Ramzan 757AH or 1356CE at the age of 82, and is buried in a part of South Delhi, India which is known as “Chirag-e-Delhi” after him.

One of his noted disciple was Khwaja Bande Nawaz Gezu Daraz, who later moved to Daulatabad around 1398, owing to the attack of Timur on Delhi, and from where at the invitation of Bahamani King, Firuz Shah Bahamani, moved to Gulbarga, Karnataka, where he stayed for the following 22 years of his life, spreading the Chishti Order in the South, till his death in November 1422. The Dargah (mausoleum) of Khwaja Bande Nawaz, exists today in the city of Gulbarga, as a symbol of multi-religious unity.

During his stay in Delhi, he continued to visit Ayodhya often, where he made a number of disciples, notably, Shaikh Zainuddin Ali Awadhi, Shaikh Fatehullah Awadhi and Allama Kamaluddin Awadhi.
