Lady Aisha (may Allah be pleased with her) narrates: The Prophet Muhammad (peace be upon him) never struck anything with his blessed hand, except when he was fighting in the way of Allah (then he attacked the enemies), and the Prophet Muhammad (peace be upon him) never struck his wife or any of his servants.
