Imam Ali ibn Abi Talib (A.S.) on Wisdom

"A fool's mind is at the mercy of his tongue and a wise man's tongue is under the control of his mind."

"There is no capital more useful than intellect and wisdom, and there is no indigence more injurious than ignorance and unawareness."

"When wisdom reaches the pinnacle of perfection, it will suppress the vicious instincts and injurious desires."

"To separate oneself from things of time and to connect oneself with things of eternity is highest wisdom."

"A wise man first thinks and then speaks and a fool speaks first and then thinks."

"Bear sorrows and calamities patiently, otherwise you will never be happy."

"Like your body your mind also gets tired so refresh it by wise sayings."

"Loving one another is half of wisdom."

"To fight against one's own desires is highest wisdom."

"Avarice dulls the faculties of judgment and wisdom."

"He is really wise whose actions reflect his words."

"The wiser a man is, the less talkative will he be."

"It is wiser to abstain than to repent."

"The wise aim at perfection."

"Many persons get nothing out of their fasts but hunger and thirst, many more get nothing out of their night prayers but exertions and sleepless nights. Wise and sagacious persons are praiseworthy even if they do not fast and sleep during the nights."

"One who takes account of his shortcomings will always gain by it; one who is unmindful of them will always suffer. One who is afraid of the Day of Judgment, is safe from the Wrath of Allah. One who takes lessons from the events of life, gets vision, one who acquires vision becomes wise and one who attains wisdom achieves knowledge."
