Islam instructs man to use his powers of
intelligence and observation.
Within a few years of the spread of Islam, great civilizations and universities
were flourishing. The synthesis of Eastern and Western ideas, and of new
thought with old, brought about great advances in medicine, mathematics,
physics, astronomy, geography, architecture, art, literature, and history.
Many crucial systems, such as algebra, the Arabic numerals, and the concept of
zero (vital to the advancement of mathematics), were transmitted to medieval
Europe from the Muslim world. Sophisticated instruments which were to make
possible the European voyages of discovery, such as the astrolabe, the quadrant,
and good navigational maps, were also developed by Muslims.
