Fanaa is a strange film. But I like this song.
The original meaning of Fanaa is from Sufi philosophy meaning annihilation of the physical self (metaphorically) and reach a state of ultimate spirituality for God. In this film, it means to completely destroy yourself in Love.

The film tells the story of blind girl Zooni who, for the first time, is travelling around India without her parents, but instead with her friends. There she meets Rehan, a tour guide and huge flirt, who at the beginning of the song is singing to her:
"If the moon is telling us to drop the veil of modesty/decency, then I want to cross the line with you*, I insist on destroying myself with you."
*If you know what I mean ;-)
Later on, the two of them go on a private trip where they do spend the night together before she has to leave and go back to Kashmir. Before she leaves on the train, Rehan takes Zooni away, and during their time together, he helps her to undergo an operation to have her sight back. Before she opens her eyes, he promises to collect her parents so they can be there when it happens.
Unfortunately, Rehan is killed in a terrorist attack, Zooni is devastated and returns back to her home and has his child.
A number of years later, another attack is planned, where it is revealed that Rehan is not dead, but in fact one of those who orchestrated the previous attack. He goes undercover into the Indian Army, where he is to make his way to Delhi to provide the vital part of the next attack. When he is found out, he escapes wounded, and lands in Kashmir. He find his way to a remote home to try and get help for his injuries. The door is opened by Zooni, who obviously doesn't recognise him, but invites him in to take care of him. He also meets his grown up son, also named Rehan.
He does eventually admit his real name, but he does not admit to who he is, and why he disappeared in the first place. What will Zooni do when she realises the person she is in love with, is planning this terrifying attack?
