It is narrated from Hazrat Anas (may Allah be pleased with him) that a man submitted in the court of the Prophet, "O Messenger of Allah (peace and blessings be upon him)! When one of us meets his friend, can he meet him by bowing down?" The Prophet (peace and blessings be upon him) said, "No." The questioner asked, "Can he embrace him and kiss him?" The Prophet (peace and blessings be upon him) said, "No." The questioner asked, "Can he shake hands with him?" The Prophet (peace and blessings be upon him) said, "Yes! If he wishes, he can shake hands."
