Hum bewafaa hargiz na the
Par hum wafa kar na sake
Humko mili uski sazaa
Hum jo khata kar na sake
Hum bewafaa hargiz na the
Par hum wafa kar na sake

Jinga lala hum jinga lala hum jinga lala hum
Hurr hurr
ho aa.. ho aa..
hurr hurr… hurr hurr…

Kitni akeli thi wo raahein hum jinpe
Ab tak akele chalte rahe
Tujhse bichhad ke bhi o bekhabar
Tere hi ghum mein jalte rahe
Tune kiya jo shikwa
Hum wo gila kar na sake
Hum bewafaa hargiz na the
Par hum wafa kar na sake

Hurr hurr..
Hurr hurr..
Hurr hurr..

Tumne jo dekha suna sach tha magar
Kitna tha sach ye kisko pata
Jaane tumhe maine koi dhokha diya
Jaane tumhe koi dhokha hua
Is pyaar mein sach jhoot ka
Tum faisla kar na sake
Hum bewafaa hargiz na the
Par hum wafa kar na sake

Jinga lala hum jinga lala hum jinga lala hum
Hurr hurr
Jinga lala hum jinga lala hum jinga lala hum
Hurr hurr
Jinga lala hum jinga lala hum jinga lala hum
