The spread of Islam throughout the Middle East and North Africa rendered Islamic much that was previously Jewish. Greek philosophy, science, medicine, and mathematics were absorbed by Jewish scholars living in the Arab world due to Arabic translations of those texts in remnants of the [[Library of Alexandria]]. Early Jewish converts to Islam brought with them stories from Jewish tradition, known as ''[[Isra'iliyyat]]'', which told of the ''Banu Isra'il'': the pious men of ancient Israel. One of the most famous early mystics of [[Sufism]], [[Hasan of Basra]], introduced numerous ''Isra'iliyyat'' into Islamic scholarship—stories that went on to become representative of Islamic mystical ideas of the piety of Sufism.

[[Hai Gaon]] of [[Pumbedita Academy]] began a new phase in Jewish scholarship and investigation (''hakirah''); Hai Gaon augments Talmudic scholarship with non-Jewish studies.  Hai Gaon was a savant with an exact knowledge of the theological movements of his time, so much so that [[Moses ibn Ezra]] called him a [[kalam|mutakallim]].  Hai was competent in arguing with followers of Qadariyyah and Mutazilites, sometimes adopting their polemic methods.  Through correspondence with Talmudic Academies at Kairouan, Cordoba, and Lucena, Hai Gaon passes along his discoveries to Talmudic scholars therein.{{Incomprehensible inline|date=February 2025}}
