“Aaj ki baat phir nahi hogi 
Yeh mulaqat phir nahi hogi
Aise badal to phir bi aayenge
Aisi barsaat phir nahi hogi”

Roughly translated…

“We will not talk about today again
Our meeting will not happen again
We will have overcast skies like this again
But we will never have the rains like this again”
