Ibn Bazz: Is it permissible for me to kiss my 70 year old cousin on her forehead over her Hijab (veil) or shake hands with her because she is very old?

Is it permissible for me to kiss my 70 year old cousin on her forehead over her Hijab (veil) or shake hands with her because she is very old? 

A: 

It is not permissible for you to shake hands or kiss her on her head or anywhere. It is permissible for you to greet her with words only even if she is old, because she is a non­Mahram (not a spouse or an unmarriageable relative). It is also permissible for you to say, "How are you?", "How are your children?", and so on. The Messenger of Allah (peace be upon him) said, I do not shake hands with women. This includes old and young women. `Aishah (may Allah be pleased with her) said, By Allah, the hand of the Messenger of Allah (peace be upon him) never touched the hand of any woman. This refers to women who were not his Mahrams. When he accepted women's oaths of allegiance to him, it was by words only.
