Tu Mujhe Soch Kabhi

It's from this movie - Zindagi Tere Naam (no clue).
Lyrics are by Jalees Sherwani. Singer is K.K.

tu mujhe soch kabhi - yahi chaahat hai meri
main tujhe ‘jaan’ kahoon - yahi hasrat hai meri
mein tere pyar ka armaan liye baitha hoon

tu kissi aur ko chaahe - kabhi khuda na kare

meri mehroom mohabbat ka sahaara tu hai
mein jo jeeta hoon to jeene ka ishaara tu hai
apne dil pe tera ehsaan liye baitha hoon
mein tere pyar ka armaan liye baitha hoon

tu kissi aur ko chaahe - kabhi khuda na kare

pyar mein shart koi ho to bataa de mujh ko
gar khataa mujh se hui ho to bataa de mujh ko
jaan hatheli pe meri jaan liye baitha hoon
mein tere pyar ka armaan liye baitha hoon

tu kissi aur ko chaahe - kabhi khuda na kare
