Men greeting Men - Men usually greet one another using the phrase ‘Salaamu Aleikum’ (it means, “peace be upon you”).  The appropriate response is Wa'aleikum as-salamma, which means, “and on peace be you.”  This is usually accompanied by a warm handshake (always use the right hand). Handshakes tend to linger a bit. “Marhaba/Hala” (or Hey!) could be used as an alternative greeting phrase as well.

Women greeting Women - Women usually greet each other in a similar manner to men.  Handshakes (always use the right hand) and/or kisses on each cheek are common.  During initial meetings, a verbal greeting is also acceptable for many people.

Greetings between Men & Women - Social interactions between non-related members of the opposite sex are not frequent, so as a result the handshake will usually not be included in the introduction.  You will be able to tell if the person you are being introduced to is leery of a handshake as they will probably fold their hands up across their chest to let you know they do not intend to shake hands.  Always wait for the woman to initiate, if at all.
