Question:
Some of my relatives (may Allah guide them) do not accept that a woman shaking hands with a non-mahram man is not permissible. When I tell them that the Messenger (peace and blessings be upon him) did not shake hands with women, they reply by saying that this is a special attribute of the Messenger (peace and blessings be upon him). Furthermore, these relatives shake hands with one another and get angry at those who forbid them. So what should we answer them? May Allah reward you with the best reward. Yes.

Answer:
As the questioner said, men shaking hands with women who are not among their mahram is forbidden and not permissible. The evidence for this is that the Prophet (peace and blessings be upon him) did not shake hands with women, and his hand never touched the hand of a woman who was not lawful for him. Rather, he would take the pledge of allegiance from women by speech. This is not specific to him (peace and blessings be upon him), but it is a legislation for his Ummah. Allah the Exalted and Majestic said: . We are commanded to follow the Messenger (peace and blessings be upon him) in this and in other matters. A special attribute for him in some rulings is not established except by evidence indicating that, and there is no evidence indicating that the non-shaking of hands with non-mahram women is a special attribute of the Prophet (peace and blessings be upon him). Therefore, not shaking hands with them is forbidden for the entire Ummah.
