As a Middle Eastern, it's quite complicated. But it is depending very very very much.
People from the gulf pay huge attention to formal greetings. Saudi men would give each other three "cheek to cheek" kiss, if a younger person met a very old person, the young would kiss the old on the forehead.This goes for parents especially, and all Arabs do it by nature.
But away from old-fashioned customs, it's mostly a handshake, some don't even handshake.
With women it very much depends on the country, some countries prohibit any kind of physical contact between genders, others allow the handshake, but never ever a kiss between men and women FOR ALL THE MUSLIM WORLD.
