Conquered Muslims held unshaken belief in rightful possession of al-Andalus

Evidence

For the Muslims there were no doubts about their entitlement to live in their homeland either. They no more thought that they might have some obligation to hand back al-Andalus, their name for it, to its original owners, the Christians, than do Egyptian Muslims today feel they should perhaps hand their country back to the Copts. — L.
