Tariq Ramadan, i hans bog Radical Reform (OUP 2009, s. 91-92):
The revealed Book neither stifles nor directs the mind, it liberates it at the heart of the Universe: the world speaks by itself, autonomously, and it is human intelligence’s task to understand its language, its vocabulary, its semantics, its rules, its grammar, and its order. The written Revelation is not a science book, but it calls on the human mind to engage all its critical, analytical and scientific potential in its quest for knowledge. Nothing is less present in the Quran than the fear or rejection of knowledge, whether sacred or profane, and this is what early scholars or scientists had felt and understood perfectly when they engaged in all the fields of learning (from philosophy to the exact and experimental sciences), confident that the absolute freedom of their reason in those fields in no way hampered the reasons and the essence of faith.
Og denne tolerante og åbne grundholdning i den tidlige islamiske civilisation var det også, som ansporede dels periodens store bidrag til videnskaber som matematik og astronomi, dels dén rolle somme kustoder af den antikke kulturarv, som araberne endte med at komme til at spille, og som senere fik en stor betydning for den eurpæiske renæssance.
Denne holdning blev senere afløst af en betydelig intellektuel stagnation, som intelligente moderne tænkere som for eksempel Tariq Ramadan forsøger at bryde blandt andet ved at vende tilbage til de første århundreders “åbne” læsning af Koranen og dens forhold til omverdenen.
