As far as male and female interaction is concerned, Islam dictates strict rules: It forbids all forms of ‘dating’ and isolating oneself with a member of the opposite sex, as well indiscriminate mingling and mixing.
If, however, one does none of the above, and all that he or she wants is to seriously consider marrying someone, such a thing itself is not considered haram. In fact, Islam encourages us to marry persons for whom we have special feelings and affinity. Thus, Islam recommends that potential marriage partners see one another before proposing marriage. Explaining the reason for such a recommendation, the Prophet (peace and blessings be upon him) said: “That would enhance/foster the bonding.”
This permission notwithstanding, we are advised against getting carried away by merely the outward appearances of a person; these may be quite misleading. Marriage is a life-long partnership and a person’s real worth is determined not by his or her physical looks, but more so by the inner person or character. Hence, after having mentioned that people ordinarily look for beauty, wealth and family in a marriage partner, the Prophet (peace and blessings be upon him) advised us to consider primarily “the religious or character factor” over and above all other considerations.
Islam does not allow any illicit relationship between a man and a woman. Allaah has established marriage as the legitimate means for satisfying sexual desire, and through marriage a man and woman form a family based on the laws of Allaah, and their children are legitimate. In Islam, there is no such thing as a girlfriend-boyfriend relationship. You are either married or you are not. To have a boyfriend or girlfriend, no matter the level of interaction and involvement, is completely haraam!
Contact between the sexes is one of the doors that lead to fitnah (temptation). Sharee’ah is filled with evidence which indicates that it is essential to beware of falling into the traps of the shaytaan in this matter. When the Prophet (peace and blessings of Allaah be upon him) saw a young man merely looking at a young woman, he turned his head so as to make him look away, then he said:
“I saw a young man and a young woman, and I did not trust the shaytaan not to tempt them.” Narrated by al-Tirmidhi (885) and classed as hasan by al-Albaani in Saheeh al-Tirmidhi.
This does not mean that it is haraam for a man or woman to like a specific person whom he or she chooses to be a spouse, and feel love for that person and want to marry them if possible. Love has to do with the heart, and it may appear in a person’s heart for reasons known or unknown. But if it is because of mixing or looking or haraam conversations, then it is also haraam. If it is because of previous acquaintance, being related or because of hearing about that person, and one cannot ward it off, then there is nothing wrong with that love, so long as one adheres to the sacred limits set by Allaah.
