DO NOT BOW TO YOUR BROTHER OR FRIEND H 901 "A man asked the Prophet, praise and peace be upon him, 'O Messenger of Allah, when one of us meets a brother or a friend should he bow to him?' He replied, 'No.' The man asked, 'Should he hug and kiss him?' He replied, 'No.' .' The man asked, ' Should he grasp his hand and shake it?' He replied, 'Yes.'" R 901 Tirmidhi with a chain up to Anas who related this.
