Islam stresses on the importance of learning and demonstrates how all the factors necessary to progress in learning God has provided. An especially vital factor is the freedom to conduct research. Such freedom was encouraged right from the beginning, as is illustrated by an incident which took place after the Prophet had migrated from Mecca to Medina. There he saw some people atop the date palms pollinating them. Since dates were not grown in Mecca the Prophet had to ask what these people were doing to the trees. He thereupon forbade them to do this, and the following year date crop was very poor as compared to the previous year. When the Prophet asked the reason, he was told that the yield depended on pollination. He then told the date-growers to resume this practice, admitting that they knew more about “worldly matters” than he did. In this way, the Prophet separated practical matters from religion, thus paving the way for the free conduct of research throughout the world of nature and the adoption of conclusions based thereon. This great emphasis placed on exact knowledge resulted in the awakening of a great desire for learning among the Muslims of the first phase. This process began in Mecca, then reached Medina and Damascus, later centering on Baghdad. Ultimately it entered Spain. Spain flourished, with extraordinary progress made in various academic and scientific disciplines. This flood of scientific progress then entered Europe, ultimately ushering in the modern, scientific age.
