mere dil mein aaj kya hai
tu kahe to main bata doon
mere dil mein aaj kya hai
tu kahe to main bata doon

teri zulf phir sawaaroon
teri maang phir saja doon
mere dil mein aaj kya hai
tu kahe to main bata doon

mujhe devta bana kar
teri chaahaton ne pooja
mujhe devta bana kar
teri chaahaton ne pooja

mera pyaar keh raha hai
main tujhe khuda bana doon
mera pyaar keh raha hai
main tujhe khuda bana doon
mere dil mein aaj kya hai
tu kahe to main bata doon

koi dhoondhne bhi aaye
to hamein na dhoondh paaye
koi dhoondhne bhi aaye
to hamein na dhoondh paaye
tu mujhe kahi chhupa de
main tujhe kahin chhupa doon
tu mujhe kahin chhupa de
main tujhe kahin chhupa doon

mera pyaar keh raha hai
main tujhe khuda bana doon
mere baazuon mein aakar
tera dard chain paaye
mere baazuon mein aakar
tera dard chain paaye

tere kesuon me chhup kar
main jahaan ke ghum bhula doon
tere kesuon me chhup kar
main jahaan ke ghum bhula doon
teri zulf phir sawaaroon
teri maang phir saja doon
mere dil mein aaj kya hai
tu kahe to main bata doon
