OK, was off a bit on that- here’s what I found:
Greetings
The Muslim handshake is called ‘salam’. A verbal greeting of ‘Assalamualaikum’ follows the salam. This means Peace be upon you’...
When extending a hand to shake that of a person of the opposite sex, a non-Muslim should not be alarmed if the handshake is not taken. This is not a rude gesture. Rather, the Muslim is abiding by the Islamic requirement that discourages physical contact between opposite sexes.
Within the Muslim community, handshaking between a younger and a respectable older person such as his father, mother or teacher goes a step further. The younger person offers the ‘salam’ first by clasping the hand of the elder and then kisses it as a sign of respect.
Right Hand and Left Hand
Muslims also believe that the right hand is better than the left. Therefore, all good and polite deeds are done using the right hand. It is considered rude to either hand over or receive something with the left hand. This hand is associated with cleansing.
