The original version of the song is sung by Rekha Bhardwaj and the reprise and redux versions are rendered by Arijit Singh and Shafqat Amanat Ali respectively. The lead actor of the film, Ranbir Kapoor, selected the version sung by Bhardwaj as one of his favourite songs from the album while stating that Singh did a good job in his rendition as well.
The lyrics include some infrequently-used Urdu wordings including "muyassar," "mukammal," "musalsal," and "badastoor." The original version by Bhardwaj uses the interplay of piano and guitar, laced with Indian sounds in the composition.[3] The reprise version by Singh is sung in a ghazal style[3][4] and has different moods in the composition, alternating between traditional tabla sounds and percussion and jazz notes with the piano.[3][5] The redux version by Ali was praised for its powerful rendition and is sung in a Sufi style.[6][7]
