Among human instincts sexual instinct is a major force attract men and women towards each other. In history sex and marriage have always been a hot topic of discussion in all religious or scientific gatherings. Some theories related to this issue, are extremist while others are normal. The followers of extremist theory believe in sexual freedom. In other hand some theories have considered sex to be an animal act and have called it filthy. We see great scholars that are the follower of this theory who never married and advised all men and women not to marry.
The sacred religion of Islam takes the balanced view and condemns both extremist views. In this view, sexual instincts are neither let loose, nor are they totally abandoned.
According Islamic teaching God has encouraged the people to get married. On the other hand, any form of sexual deviation or being loose is seriously fought with.
Prophet Muhammad (Peace Be Upon Him and His Progeny) has said:“O young people! Any of you who have the means to marry should do so since this is the best way to protect your eyes from corrupt and treacherous looks, and to guard the private parts from sin and immodesty. Whoever does not have the means to marry should fast continually since fasting can reduce lust.”(Makarim al-Akhlaq, p.196)
The human eye is like other tools. It means if we use it correctly the result will be good and vice versa. We are not allowed to use our eyes as we wish, as we are not allowed to use a knife to injure or kill others. Hence, prohibited items must be known to avoid committing them. For example it is forbidden to look at unfamiliar (Na-Mahram) women. It does not mean that we should close our eyes completely since then we cannot walk or we might fall down on the ground, but it means we can reduce the amount that we see by limiting our view. Imam Sadiq (the sixth Imam of Muslims) said:“One look after another will sow the seeds of desire in the heart, and it is sufficient temptation for the person.”(Wasa’il al-Shi’ah, v.14, p.139)
A dirty look will also tear down the veils of modesty and chastity. There are many people whose life is ruined due to a dirty look. Only for instance it can be said that dirty look of a married man at unfamiliar (Na-Mahram) woman or girl will sow the seeds of desire in his heart and he will be in love with her gradually and it can ruin the family. And it is also forbidden for women because the same reason.
We should remember that dirty look, is a major reason for the spread of adultery.
