Imam Ali (s) says,

“A faithful one is truthful in the worldly life, with an insightful heart. He keeps to the (moral) limits. He is a vessel of knowledge, with perfect thinking. He is generous, good-hearted, patient, and openhanded. He spends liberally. He is charitable, honey-tongued, and smiling. He ponders much, sleeps little, and laughs little. He is with good manners, free from greediness, and away from fancy. He is ascetic in this life. He looks forward to the afterlife. He likes guests. He is merciful to the orphans. He is kind to the young. He has regard for the old. He helps the needy, visits the sick, and escorts the dead. He respects the holiness of the Qur’an, prays to the Lord, cries for sins, enjoins right, forbids wrong, eats little, drinks little, moves with politeness, speaks with advice, and preaches kindly. He does not fear any except Allah and expects no one save Him. He is busy in thanking and praising Allah. He is neither negligent nor is he proud. He is not proud of the properties of the worldly life. He is busy thinking of his own defects away from the defects of others. Prayer is the delight of his eyes. Fasting is his job and occupation. Truthfulness is his habit. Gratefulness is his ship. Reason is his captain. Piety is his food. The worldly life is his prison. Patience is his home. The night and day are his capital. Paradise is his abode. The Qur’an is his speech. Muhammad is his intercessor and Allah the Almighty is his entertainer.”
