OK, then name same.  Math? That came from the Greeks.Science?  GreeksNavigation?  GreeksThe western alphabet and writing? Phoenicians, Greeks, then Romans.Anything that Islam did was a continuation and/or copy of Graeco-Roman contributions.I'll give them this (and this was before Islam), the Arabs preserved a lot of ancient text (but so did the Irish and Benedictine monks)So here's a better question.  What ORIGINAL contribution did Islam make to western civilization?

Easy:Following the fall of the Roman Empire and the dawn of the Middle Ages, many texts from Classical Antiquity had been lost to the Europeans. In the Middle East however, many of these Greek texts were translated from Greek into Syriac during the 6th and the 7th century by Nestorian or Jacobite monks living in Palestine, or by Greek exiles from Athens who visited Islamic Universities. Many of these texts were then kept, translated, and developed upon by the Islamic world, especially in centers of learning such as Baghdad with thousands of manuscripts existed as soon as 832. These texts were translated again into European languages during the Middle Ages.Islamic world developed its own sciences, such as algebra, chemistry, geology, trigonometry and more which were later also transmitted to the West.  Contributing to the growth of European science was the major search by European scholars for new learning which they could only find among Muslims, especially in Islamic Spain and Sicily. These scholars translated new scientific and philosophical texts from Arabic into Latin. (see Averroes)The chemical and alchemical works of Geber (Jabir ibn Hayyan) were translated into Latin around the 12th century and became standard texts for European alchemists.Arabic astronomical and mathematical works were translated into Latin during the 12th century. Arabic numerals are the ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). From there they were transmitted to Europe in the Middle Ages.Hospitals began in the Islamic world and later spread to Europe during the Crusades, inspired by the hospitals in the Middle East.  The first hospital in Paris, Les Quinze-vingt (15/20), was founded by Louis IX after his return from the Crusade between 1254-1260.One of the most important scientific works to be translated was Ibn al-Haytham's Book of Optics (1021), which initiated a revolution in optics and visual perception and introduced the earliest experimental scientific method.In the 12th century, Europe owed Islam an agricultural revolution (see Muslim Agricultural Revolution), due to the progressive introduction into Europe of various unknown fruits: the artichoke, spinachs, aubergines, peaches, apricots.Europe adopted a number of educational, legal and scientific institutions from the Islamic world, including the public hospital and psychiatric hospital, the public library and lending library, the academic degree-granting university (e.g. Madrasah :the origins of the college lies in the medieval Islamic world), the astronomical observatory as a research institute.From Islamic Spain, the Arabic philosophical literature was translated into Hebrew, Latin, and Ladino, contributing to the development of modern European philosophy (check Avicenna.) Need more ?  😉The fact that there is some conflicts around the world and especially with Islamic appearance shouldn't mislead our judgement about any civilisation.  History is not a valet of politics.

That is true.  And it's too bad that many postmodern historians, when trying to amplify the contributions of Islam, are ignoring real history in the process.

Well Sky, I'm not trying to amplify anything but I like to tickle and tease people until they finally reckon that when they are dealing with History: appearances, news, preconceived opinions make the historian's work "difficult" ...

BTW, it took me less than 15 minutes to find those 3 links.  It's not that difficult to present historical fact sometimes.  ;D

Agreed  😉

When it gets right down to it, I am not very interested in discussing causes for terrorism.  I care about solutions.
