Enjoinment of Self-Scrutiny

Imam Ali (AS) said, 'Appoint your own self as a scrutinizer over yourself, and use this world to reserve your share in the Hereafter.

Imam Ali (AS) said, 'Man must control and survey his own self, scrutinize his heart, and guard his tongue.

Imam Ali (AS) said, 'Allah has mercy on the servant who scrutinizes his sins carefully and fears his Lord.

Imam Ali (AS) said, 'The rational man must calculate his soul's misdeeds against religion, reason, ethical virtues and good moral conduct. He must gather this information within himself or write it down in a book and work at eradicating them.

Imam al-Sadiq (AS) said, 'The man for whom each day passes exactly the same as another [where there is no change in his character or his deeds] is indeed a loser. And the man for whom the next day is always worse than the previous day is indeed cursed. And the man who never sees to improve himself day after day is indeed at a loss, and whoever passes his days in such loss, death is surely better for him than life.
