Razia Sultan is a 1983 Indian period biographical film, written and directed by Kamal Amrohi, and starring Hema Malini, Parveen Babi and Dharmendra in lead roles.

Once Kamal Amrohi and his wife Meena Kumari liked a song that they had listened to on the radio.

The song was "Parbaton Ke Pedon Par" and was sung by Mohammed Rafi and Suman Kalyanpur.

When Kamal went to the duo's place to listen to their new tune, he was asked to wait as the music directors were in a meeting.

Feeling insulted that he was asked to wait by someone so junior to him, Kamal Amrohi replaced them with Khayyam.
