Adaab!
I’ve recently started to become interested in north indian classical music [ie hindustani classical]–zaahir hai ke iss mein pakistani musiqaar bhi mawjood hain.
So far I have really enjoyed instrumental music on the sitaar especially the following raags:
raag bhimpalaasi
raag miyaaN ki malhaar
raag darbari
raag bhairvi
also some vocal classical by Ustad BaRe Ghulam Ali Khan; Mehdi Hassan too has some ghazals in classical raags 
I would like some other recommendations…
