Is it forbidden to shake hands with a non-mahram woman?

السؤال:
He says: I have heard from some people that greeting a woman without a barrier on her hand is considered a forbidden act. Is this correct?
Answer:
It is not permissible for a believer to shake hands with women unless he is a mahram to her, such as her brother, her uncle, or the like. The Prophet (peace and blessings be upon him) said: “I do not shake hands with women” when he was taking their pledge of allegiance. When a woman wanted to shake his hand, he said: “I do not shake hands with women”. Aisha (may Allah be pleased with her) said: “The hand of the Messenger of Allah (peace and blessings be upon him) never touched the hand of a woman. He only took their pledge of allegiance through speech.” Therefore, it is obligatory not to shake hands with a non-mahram woman, even if there is a barrier. One should greet her with words, and that is sufficient; there is no need for handshaking. This is because handshaking leads to fitnah (trial, discord or temptation), just as looking does. It is obligatory that the greeting be without handshaking. One should say, “How are you, so-and-so? How are your children? How is your husband? How is your father?” and the like, without handshaking. He also must not be in seclusion with a non-mahram woman. He must not shake her hand or be in seclusion with her, but rather greet her without seclusion, unless she is a mahram to him, such as his sister, his aunt, his mother, his daughter, or the like, in which case there is no harm in it. One should not be lenient in these matters, as they may lead to consequences that are not praiseworthy. We ask Allah for guidance and well-being for everyone. Yes.
