Bowing when we greet

Q74 :What is the Islamic view of bowing when we greet someone?

A74 : Any action which is similar to an act of worship is forbidden in Islam when it is offered to anyone other than Allah. To bow one's head or to do any similar gesture when one meets another person is to do something akin to an act of worship. Therefore, it is unacceptable from the Islamic point of view. As you realize, bowing is part of our prayer. Even when you do not bow fully as you do in prayer, to lower your head in order to greet someone falls in the same category as doing something which is similar to worship, but you are offering it to a human being. That cannot be sanctioned by Islam.
