Sabra، A. I. (1996)، "Situating Arabic Science: Locality versus Essence"، Isis، ج. 87، ص. 654–670، DOI:10.1086/357651، JSTOR:235197. «"Let us begin with a neutral and innocent definition of Arabic, or what also may be called Islamic, science in terms of time and space: the term Arabic (or Islamic) science the scientific activities of individuals who lived in a region that might extended chronologically from the eighth century A.D. to the beginning of the modern era, and geographically from the Iberian Peninsula and north Africa to the Indus valley and from the Southern Arabia to the Caspian Sea—that is, the region covered for most of that period by what we call Islamic Civilization, and in which the results of the activities referred to were for the most part expressed in the Arabic Language. We need not be concerned over the refinements that obviously need to be introduced over this seemingly neutral definition."»
