Imam Ali ( as ) Said:
The one who teaches me but a single word makes me his servant.

One who asks questions learns.

Every thing is good when it is new but friends who are good when they are old.

Don’t speak when you find it untimely.

The best of all men is one who is the most useful to the people.

If you love God clear from your heart the love of the world.

Don’t close a door that you are unable to open.   

One who is content with little needs not much.

A true believer will not eat fully as long as his brother is hungry.

How can you be happy in this life than grows shorter with the passage of every hour? 

The one who is unable to keep his own secrets will never be able to keep the secrets of others.
