Answer:
To preface, we're in between the time of 1200 CE - 1450 CE.
Sacred Islamic texts such as the Quran and the Hadith placed a vehement emphasis on both education and scientific discovery, regardless of the origin. This meant that in Muslim states, non-Islamic religious texts were read from, learned from, translated, et cetera.
Muslim rulers were also tolerant of other religions through the following of Sharia law and acknowledgement of "People of The Book," (in reference to followers of other Abrahamic religions), or Dhimmi. Dhimmi, in this context, followers of Judaism and Christianity, were allowed to reside and practice their faith in Muslim states by paying the Jizya tax.
