dost dost na raha
pyaar pyaar na raha
zindagi hamein tera
aitbaar na raha
aitbaar na raha

dost dost na raha
pyaar pyaar na raha
zindagi hamein tera
aitbaar na raha
aitbaar na raha

amaanatein main pyaar ki
gaya tha jis ko saunp kar
wo mere dost tum hi the
tum hi to the

jo zindagi ki raah mein
bane the mere hum safar
wo mere dost tum hi the
tum hi to the

saare bhed khul gaye
raaz daar na raha
zindagi hamein tera
aitbaar na raha
aitbaar na raha

gale lagi sehem sehem
bhare gale se bolti
wo tum na thi to kaun tha
tum hi to thi

safar ke waqt men palak
pe motiyon ko tolati
wo tum na thi to kaun tha
tum hi to thi

nashe ki raat dhal gayi
ab khumaar na raha
zindagi hamein tera
aitbaar na raha
aitbaar na raha

wafa ka le ke naam jo
dhadak rahe the har ghadi
wo mere nek nek dil
tum hi to ho

jo muskura ke reh gaye
zeher ki jab sui gadi
wo mere nek nek dil
tum hi to ho

ab kisi ka mere dil
intezaar na raha
zindagi hamein tera
aitbaar na raha

dost dost na raha
pyaar pyaar na raha
zindagi hamein tera
aitbaar na raha
aitbaar na raha
