As for Islam, the orthodox conception of Allah is hostile to the scientific quest. There is no suggestion in the Qur'an that Allah set his creation in motion and then let it run. Rather, it is assumed that he often intrudes in the world and changes things as it pleases him. Thus, through the centuries many of the most influential Muslim scholars have held that all efforts to formulate natural laws are blasphemy in that they would seem to deny Allah's freedom to act. Thus did people's images of God and the universe deflect scientific efforts in China, ancient Greece, and Islam.
