Imam Ali (as), in his letter to Malik al-Ashtar when he appointed him governor of Egypt, said, Do not keep yourself secluded from the people for a long time, because the seclusion of those in authority from the subjects is a kind of narrow-sightedness and causes ignorance about their affairs. Seclusion from them also prevents them from the knowledge of those things which they are unaware of and as a result they begin to regard big matters as small and small matters as big, good matters as bad and bad matters as good, while the truth becomes confused with falsehood.
