Even during reign of 4 "rightly guided Khalifs", when Islamic army invaded lots of areas outside Arabian Peninsula, THERE USED TO BE SEPARATE QUARTERS, RIGHTS OF NON-ARAB AND ARAB MUSLIMS.
EVEN ARAB AND NON-ARAB MUSLIMS DID NOT HAVE EQUAL RIGHTS TO WAR BOOTY.
Equality in Islam is a after thought inserted by Islamists post French revolution.
