i think that Ishq is different from love. Ishq is very much used in Farsi, but, nobody can tell what it really is. The Qur'an teaches us to use our reason and not to follow blindly our desires and Satan. Here in Iran there are people who claim on their mouth Ishq for Exalted Prophet (S) and Ahlil-Bayt and in action reject Allah and Truth.
Even if Ishq is so positive and devine !!! then i prefer to follow the Qur'an and not Ishq. Though i don't understand what Ishq is !
