This was Vishal Bhardwaj's recreation of a popular ghazal composed and sung by Mehdi Hassan.[1]
Concerned that he wouldn't be able to do justice to the song, Arijit Singh evaded rehearsals on the pretext that he had to go out to smoke. The singer refused to return to the studio despite filmmaker, music director Vishal Bhardwaj's entreaties. Arijit sent Bhardwaj his recording of the song later and recorded the song in the studio after the filmmaker convinced him that he was ready.[2]
