In Islam, the concept of love is one of the most important concepts. This fact manifests itself in Islamic philosophy, theology, mysticism and ethics; indeed, in some aspects, it plays the crucial role. For example, in defining the Islamic point of view on the relation between God and Universe in general, and between God and Mankind in particular, love has the most significant and profound place. Love is so central in Islam that it is seep as “the firmest handhold of faith” and “faith (Iman) is nothing but love for the sake of God and hate for the sake of God”.
Ibn Abbas reported that Messenger of Allah (Peace and blessings of Allah be upon him and his family) said: “The strongest faith is to be sincere for the sake of Allah, to hate for the sake of Allah (Tabarra), to love for the sake of Allah (Tawalla), and to discard for the sake of Allah.”
There is a tendency among some people to think that there should be no hate at all. These people assume that excellence and nobility of character and “being sociable” consist of having all men one’s friends. Certainly Islam recommends Muslims to love people and optimize compassionate and sincere relationship with them, even if they do not believe in Islam or in God. However, it is not feasible for a person who has principles in his life and has devoted his life to realize sacred values to be indifferent to evil and oppressive deeds of wrongdoers and make friendship with everybody. Such a person certainly will have some enemies, whether he likes it or not. There are always good people in the society and bad people. Good and bad are two opposite poles. Attraction towards the good is not possible without repulsion from the bad.
