Dialogue: "Ho mere hothon pe tere hothon ki pyaas aise jagi, man mere bhi tan tere bhi aag jalne lagi, ho sard mausam hai garam aalam hai dil mein toofan hai, beqarari hai kya khumari hai kitne arman hai, meri jaan keh rahi hai mujhpe jaan nisaar kar lo, jitna beqaraar hoon main khud ko beqaraar kar lo, meri dhadkanon ko samjho tum bhi mujhse pyaar kar lo."
