Handshaking that involves skin contact with a person of opposite sex is prohibited. One can use gloves to prevent skin contact.
It is best to apologize for not doing such an action by stating that our religion does not allow it.
Some people who do not understand the religion or do not believe in it might think that this law is disrespectful to women, but this false notion originates from being distanced from the environment of Muslims and not knowing the details of their religion, since the prohibition of hand shaking is not limited to men but it also includes women as well as they are not permitted to shake menâ€™s hand. It is purely a legislation that could mean â€“ based on our understanding â€“ placing borders between men and women to protect their chasteness and to help in preventing them from falling into prohibited acts.
