Idris narrates that Wahb bin Munabbih said: "It is easier for Satan to uproot mountains stone by stone than to deceive an intelligent and discerning believer. For such a believer is more steadfast than a mountain and tougher than iron. Satan tries every trick to deceive him but fails. Frustrated, he exclaims to himself, 'Woe unto me! Why can't I overcome him?'." This book derives from the great works of Ibn Jawzi and Ibn Qayyim (Allah have mercy on them) and outlines the steps to become an intelligent Muslim. It contains narrations of both the fools and the intelligent people so that we can learn from their stories.
