The opening as it read in 2005

Photo taken from medieval manuscript by Qotbeddin Shirazi, an Astronomer. The image depicts a star constellation. Islamic science is science in the context of traditional religious ideas of Islam , including its ethics and prohibitions. This is not the same as science as conducted by any Muslim in a secular context. However, certain liberal movements in Islam eschew the practice of Islamic science, arguing that science should be considered separate from religion.1
