The ruling on shaking hands with an elderly woman

Question:
May Allah send you well, and this questioner is asking about shaking hands with an elderly woman

Answer:
A woman must not shake hands with a man who is not her mahram (a relative one may not marry), even if she is elderly, because the Prophet (peace and blessings be upon him) did not shake hands with women. Aisha (may Allah be pleased with her) said: It was never permissible for him. He would pledge allegiance to women by words, not by shaking hands. A woman who is not a mahram must not shake hands, even if she is elderly. The salam (greeting) is given without shaking hands; it is given by words. Greet her by words while she is veiled.
