Yes it is an Islamic greeting....a man person say to another when he/she meet to him. which means "'May God take care of you and full fill your desires"".

yes , i agree with hany
initially it used to be an islamic greeting in the early times of islam, then with the expantion of islam in all the arabic peninsula ,it became
an arabic greeting too
now it is an arabic greeting wich includes non muslims arab-people greetings
of course non arab muslims use the greetings they have in their mother tongue

no,
Is not for Muslims
Why all of you say yes, this is a mistake
True, they are greeting Muslims but that does not mean she can't be used
you can use it
But better to use the other greeting ^.^
