'Paharon Ki Qasam' was originally sung by Kamal Masood. Singer Ali Zafar has released a tribute to Muhammad Ali Sadpara, a Pakistani mountaineer who went missing while climbing the K2 on February 9. 'Paharon Ki Qasam' was originally sung by Kamal Masood. Zafar's version of the song also features the traditional instruments used in the original version. It has been produced by his production house Lightingale Records. The video features a compilation of shots of Sadpara and scenic shots of the mountains. The lyrics are especially poignant given that the entire nation is praying for Sadpara's safe return. "We haven't gotten word of your arrival. Your memory won't leave our hearts," croons Zafar.
