The Quran mentions the story of Moses and Khidr [a prophet mentioned in the Quran who guided Moses on a revelatory journey], a famous story, in which Moses represents sort of the external understanding of the religion and Khidr represents the inner spiritual understanding of the religion.

It is for Muslim scholars to study the whole history of Islamic science completely and not only the chapters and periods which influenced Western science. It is also for Muslim scholars to present the tradition of Islamic science from the point of view of Islam itself and not from the point of view of the scientism, rationalism and positivism which have dominated the history of science in the West since the establishment of the discipline in the early part of the 20th century in Europe and America.
