What does Islam say about falling in love?

"If we are speaking about the emotion which we call "love" then we are simply speaking of a feeling. What we feel toward a particular person is not of great importance, until our feeling is expressed in a particular action. Now if that action is permissible, then well and good. If it is forbidden, then we have incurred something that Allah does not approve of. If it is love between a man and a woman, the emotion itself is not the subject of questioning on the Day of Judgment. If you feel you love someone, then you cannot control your feeling. If that love prompts you to try to see that person in secret and to give expression to your feelings in actions permissible only within the bond of marriage then what you are doing is forbidden."
