It is essential for anybody to know his or her partner well enough before marriage so that he or she may decide whether to go in matrimonial relation with that person or not. So for that purpose, dating is allowed in Islam or not?
Please don't compare it with love before marriage. Because there's always a possibility that a man is dating some woman just to know her so that he may decide whether she is a right for him or not, but at that moment he hadn't fallen in love with her.
