The 92-year-old composer was taken to Sujay hospital on Sunday.
"He is right now in ICU, serious but stable. Doctors are attending to him. At this point, we don't know when he will get discharged from the hospital but we are all praying for his speedy recovery," Ghazal singer Talat Aziz, a close family friend of Khayyam, told PTI.

He is also a recipient of Sangeet Natak Akademi Award and Padma Bhushan.
