these are my favourite one is from mohobaatein and other one from kal ho na ho shahrukhs movies
"Pyaar zindagi ki tarah hota hai, Jiska her morr aasan nahi hota, Her raste per khushi nahi milti, Per jab hum zindagi ka saath nahin chorte, To hum pyaar karna kyon chorein..." this is from mohobatein
"Aaj... Aaj ek Haseen aur baant loon... Aaj ek Dua aur mang loon...Aaj ek aansoo aur pee loon... Aaj ek Zindagi aur ji loon...Aaj ek Sapna aur dekh loon...Aaj... Kya pata Kal Ho Naa Ho!!!" and this one is from kal ho na ho
