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. Moses went on a journey with Khidr and Khidr said, "I will not accept you unless you stop questioning things," which from an external point of view seems strange, but inwardly is very meaningful. This is exactly the question of spiritual guidance.
