A man's measure is his will.

— Ali ibn Abi Talib

Be like the flower that gives its fragrance to even the hand that crushes it.

Do not share the knowledge with which you have been blessed with everyone in general, as you do with some people in particular; and know that there are some men in whom Allah, may He be glorified, has placed hidden secrets, which they are forbidden to reveal.

— Ali ibn Abi Talib

Don't count the days. Make the days count.

Half of wisdom is love and friendship with people.(the other half is to guard yourself against the evils of people)

— Ali ibn Abi Talib

He who has a thousand friends has not a friend to spare, And he who has one enemy will meet him everywhere.

— Ali ibn Abi Talib

I am amazed at the heart of man: It possesses the substance of wisdom as well as the opposites contrary to it ... for if hope arises in it, it is brought low by covetousness: and if covetousness is aroused in it, greed destroys it. If despair possesses it, self piety kills it: and if it is seized by anger, this is intensified by rage. If it is blessed with contentment, then it forgets to be careful; and if it is filled with fear, then it becomes preoccupied with being cautious. If it feels secure, then it is overcome by vain hopes; and if it is given wealth, then its independence makes it extravagant. If you want strikes it, then it is smitten by anxiety. If it is weakened by hunger, then it gives way to exhaustion; and if it goes too far in satisfying its appetites, then its inner becomes clogged up. So all its shortcomings are harmful to it, and all its excesses corrupt it.

— Ali ibn Abi Talib

If all the women over the world have been permitted to be married to only one man, except one woman. He'd love to marry that woman. That is the imprint of man

— Ali ibn Abi Talib

If one night you see someone committing a sin, tomorrow do not look at him as a sinner. He may have repented during the night, and you did not know.
