Not sheking hands with the opposite gender

Not shaking hands with the opposite gender - the Hijab of men exemplified by Prophets. It is not uncommon for non- Muslims and even many Muslims to associate the Islamic commandments on Hijab with females, even though Islam has ordained Hijab for both men and women. In fact, many of us would be surprised to note that Allah states in the Holy Qur'an: "Tell the believing men to cast down their looks and guard their private parts; that is purer for them; surely Allah is Aware of what they do. And tell the believing women that they cast down their looks and guard their private parts and do not display their ornaments except what appears thereof...." (24:30-31) Indeed, before addressing women and telling them to conceal their bodies, Allah first addresses the believing men and tells us to lower our gaze! When discussing the issue of Hijab for men, it is essential to keep in mind the Golden Rule: do unto others as you would have them do unto you. A man once came to the Holy Prophet (peace be upon him and his progeny) and told him he wished to commit fornication. As the companions got up to strike him, the Prophet restrained them and then said to the man, "My son, how would you feel if someone wished to do the same thing with your mother or sister or wife or daughter?" The man replied that naturally he would want to kill the person. The Prophet then said, "If you do not wish for someone to do such an act with your mother or sister or wife or daughter, then why entertain such a thought about someone else's mother or sister or wife or daughter?!" Islamic teachings on Hijab for males can be divided into three categories:
physical,eye and social.
