Is it permissible to shake hands with a non-mahram woman if she is advanced in age?

Question:
Is it permissible for me to shake hands with my female relatives who are not mahram if they are in their sixties?

Answer:
A man does not shake hands with women who are not his mahram. Even if she is old, whether she is sixty, seventy, or a hundred, he does not shake her hand. This is because the Prophet (peace and blessings be upon him) did not shake hands with women during the pledge of allegiance; he pledged with them using only words and did not shake their hands. Aisha (may Allah be pleased with her) said, "His hand never touched the hand of a woman who was not lawful for him." Therefore, it is not permissible for a man to shake hands with a woman who is not his mahram, even if she is old. Yes.
