Ek bar muskura do
Ek bar muskura do
Kaha se uthhe hain
Kadam yaad rakhana
Mohabbat ki pahali
Kasam yaad rakhana


Kaha se uthhe hain
Kadam yaad rakhana
Mohabbat ki pahali
Kasam yaad rakhana
Kaha se uthhe hain
Kadam yaad rakhana
Ek bar muskura do


Yeh mandir ki
Diwar sadiyo purani
Yeh mandir ki
Diwar sadiyo purani
Kahegi hamari
Tumhari kahani
Kahegi hamari
Tumhari kahani


Yeh mandir hain ghar
Pyar ke dewata ka
Yeh mandir hain ghar
Pyar ke dewata ka
Kahi tum ne chhoda
Jo daman wafa ka
Kahi tum ne chhoda
Jo daman wafa ka


Yahi jan de denge
Ham yaad rakhana
Mohabbat ki pahali
Kasam yaad rakhana


Yahi jan de denge
Ham yaad rakhana
Mohabbat ki pahali
Kasam yaad rakhana


Ek bar muskura do
Ek bar muskura do
Ek bar muskura do.
