And he said: “By the One in Whose hand is my soul, you will not enter Paradise until you truly believe, and you will not truly believe until you love one another. Shall I not tell you of something that, if you do it, you will love one another? Spread (the greeting of) salaam amongst yourselves.” (Narrated by Muslim, 54)
Love in Islam is more general and more comprehensive; it is not restricted only to one kind of love, that between a man and a woman. There are many more kinds of love. There is the love of Allaah, love of His Messenger (peace and blessings of Allaah be upon him) and his companions (may Allaah be pleased with them), love for good and righteous people, love and support for the religion, love of martyrdom for the sake of Allaah. There are many kinds of love. It is a dangerous mistake to restrict this broad meaning to this one kind of love.
