90% of these are incorrect.
For example, Aristotle wrote in 300 bc that the world was round. Nearly a thousand years before Islam was created. Gallileo was not the western man credited with discovering the world was round... that was Copernicus.
Also many of the discoveries attributed to 'Islam' were actually attributed to Middle Easterners, but way before 600AD, which is before the Prophet Muhammed and the creation of Islam.
Henry the V's castle? Which one? Most of the castles of England (and indeed western Europe were built from 1000 to 1300AD, Britain's most famous castles were built by Edward I. The castle Sant Angelo in Rome was built by the Romans for Emperor Hadrian.
Also, some of Islam's most famous architecture was copied from the Byzantines, in the case of Hadj Sofia, stolen completely.
Irrigation was used by the ancient Egyptians 2000 years before the birth of Christ, so was paper, soap, perfumes, hospitals, music, cosmetics.. etc etc etc.... is this claim being made simply because Egypt is now a Muslim country? In which case this is a lie, because the ancient Egyptians had nothing in common with Islam.
