Jab Tak Hai Jaan

Jab tak hai jaan

Teri aankhon ki namkeen mastiyan
Teri hansi ki beparwaah gustakhiyaan
Teri zulfon ki leharaati angdaiyaan
Nahi bhoolunga main
Jab tak hai jaan, jab tak hai jaan

Tera haath se haath chhodna
Tera saayon se rukh modna
Tera palat ke phir na dekhna
Nahin maaf karunga main
Jab tak hai jaan, jab tak hai jaan

Baarishon mein bedhadak tere naachne se
Baat baat pe bewajah tere roothne se
Chhoti chhoti teri bachkani badmashiyon se
Mohabbat karunga main
Jab tak hai jaan, jab tak hai jaan..

Tere jhoothe kasme vaadon se
Tere jalte sulagte khwabon se
Teri be-raham duaaon se
Nafrat karunga main
Jab tak hai jaan, jab tak hai jaan
