Kun Faaya Kun, a qawwali from Ranbir Kapoor-Nargis Fakhri starrer Rockstar is creating a lot of buzz. The music video was shot at Nizamuddin Dargah in Delhi.

AR Rahman, Javed Ali and Mohit Chauhan have sung this song.

The qawwali was shot at Hazrat Nizamuddin Dargah in Delhi as the place is very close to director Imtiaz Ali's heart. During the shoot of the song, Ranbir also stayed at the Dargah for a couple of days. Rockstar's music composer AR Rahman has also often expressed his reverence for the place.

The cast of the film recently launched the music at the Nizamuddin Dargah. Ranbir, who was dressed in a cream kurta teamed with a pair of jeans, played the guitar himself, while singer Mohit sang the soulful number. What followed was an hour-long qawwali session.

This is also late legendary actor Shammi Kapoor's last film. He'll be seen in a jugalbandi sequence with his grandnephew Ranbir. Ranbir will strum a guitar while Shammi will play a shehnai.

The film is scheduled for a November 11 release (11.11.11) which is considered to be a lucky date.
