BEAUTIFUL SONG

I am not going to write anything about today's episode as much has been said and written about..Like everyone I am also sad about but I am positive this will strengthen Asad and Zoya's relation more.
Coming to my topic today the quwaali song they played was beautiful I know they played this song in the first episode but today the entire extented version of it was beautiful.I simply loved it

can someone tell me the name of the song please?
