He served in the court of Mughal Emperor Muhammad Shah (ruled 1719-1748). Sadarang and Adarang remain influential in Hindustani classical music, mainly through their compositions. Salar Jung Nawwab Dargah Quli Khan, a young noble deccani who lived in Delhi between 1737 and 1741, had the opportunity to hear Na’mat Khan play the bin.
He wrote in Risala Salar Jung later translated as Muraqqa -i Dehli: “When he begins to play the bin, when the notes of the bin throw a spell on the world, the party enters a strange state: people begin to flutter like fish out of water (…). Na’mat Khan is acquainted with all aspects of music. Na’mat Khan is considered unequalled and is the pride of the people of Delhi. Niyamat khan was the descendant of Naubat Khan. Another Famous descendant of Sadarang was Wazir Khan of Rampur.
