ya, the muslim religion is the newest, but the lineage goes back to Abraham who had 2 sons: Jacob, and that bastard child (the name escapes me). Jacob, who had his name changed to 'Isreal' is the beginning of the lineage for jews. The bastard child is the beginning of the lineage for the arabs. There are predictions in the Bible that the 2 brothers/nationalities would never get along.
Even if you don't believe in christianity, the Bible is a darn good history book.
