He creates densely layered imagery that is both abstract and figurative and addresses narratives of history, cumulative experience and the metaphysical collapse of time into single moments.

[4] Khan's photographs or scans originate from secondary source material – for instance, every page of the Qur'an, every Beethoven sonata, every William Turner postcard from Tate Britain, or every Bernd and Hilla Becher spherical gasholder.

"[9] As Khan describes: "It is a challenge to not define my work as a photograph but using the medium of photography to create something that exists on the surface of the paper and not to be transported back to an isolated moment in time.

"[9] He takes inspiration from Samuel Barber’s Adagio for Strings and Antonio Vivaldi's The Four Seasons and made a ballet with Wayne McGregor and Max Richter.

[12] Also in 2012, The New York Times Magazine commissioned Khan to create a new body of work that was published in their London issue,[13] focusing on iconic sites.
