Islamic Civilisation - what came of it?

Re: Islamic Civilisation - what came of it?

the words taqlid and asibiyah are probably the answer..all empires rise and fall..that is the nature of life. Muslim navigators did not bother to uncover the route around the cape of Good hope or the Americas despite the fact that it was their navigation equipment and navigators who helped the Spanish and Portugese uncover them..c'estla vie..some nations reach the ends of the earth and turn back..others reach the moon and turn back

Despite the lack of innovation the Muslim Empires represented a significant chunk of the world economy..what was lacking was a zeal or determinatiwhich again comes back to what i said in that first sentence
