The definitive

Because the decisive ones are: everything established with certain evidence, which protects the mind from deviation, due to its precision and strong intellectual structure, and any flaw in it is a cause of corrupting thinking. And since the decisive ones have an effect in achieving intellectual and doctrinal security, any flaw that affects these decisive ones will mean falling into a pit of illusions, doubts, and confusion under the cover of dark darkness from bewilderment and losing the ability to think and make decisions, as has happened and happens with the suspicious and those afflicted with whispers. The judgment of the decisive ones is what will lead to steadfastness on the principle, and steadfastness is the cause of psychological stability and the cause of feeling safe and reassured.
