I’m assuming you meant "NFAK" as in "Nusrat Fateh Ali Khan",

the legendary Pakistani Qawwali singer.

Throughout his career, NFAK received numerous awards and accolades, including the Pride of Performance award. Nusrat Fateh Ali Khan passed away on August 16, 1997, but his music continues to inspire and influence generations of artists and fans.
