Kun-existence and fayakun its consistency.
The exact and short meaning is from the time human is made , there’s a feeling on loneliness or you may say that human thinks that he’s is incomplete, there’s something missing. So Kun Faya Kun is that call (pukar) to allah in which human says “please complete me”. Mirza Galib has describe this in beautiful line that
na thā kuchh to ḳhudā thā kuchh na hotā to ḳhudā hotā
Duboyā mujh ko hone ne na hotā maiñ to kya hota
Kun Faya Kun Meaning: The origin is from the arabic words “Kun” which means “to be” or “to exist” & “Faya Kun” means “it is”. So the literal translation of Kun Faya Kun is “Be ,and it is”.
Kun Faya Kun is one of the rare songs that had me totally floored from the first moment I heard it. Easily one of AR Rehman’s and Irshad Kamli’s finest works, the beauty of the song is not just in the words or the music but in the complete conceptualization.
