“Oh threats of Hell and Hopes of Paradise!One thing at least is certain - This Life flies;One thing is certain and the rest is Lies -The Flower that once has blown forever dies.” 

Omar Khayyam

“A writer should never write a book except with the assumption that all people are his enemies, have full knowledge of all matters, and have nothing better to do than critique his work.

Al-Jahiz

“The desires of this world are like sea water. The more you drink of them, the more you thirst.” 

Ibn Arabi

“The composing of books is more effective than building in recording the accomplishments of the passing ages and centuries.

For there is no doubt that construction eventually perishes, and its traces disappear, while books handed from one generation to another, and from nation to nation, remain ever renewed... Were it not for the wisdom garnered in books most of the learning would have been lost.

The power of forgetfulness would have triumphed over the power of memory.

Al-Jahiz

The knowledge of anything, since all things have causes, is not acquired or complete unless it

is known by its causes.

Avicenna

The world is divided into men who have wit and no religion and men who have religion and no wit.

Avicenna

“As far as you can avoid it, do not give grief to anyone. Never inflict your rage on another. If you hope for eternal rest, feel the pain yourself; but don’t hurt others.” 

Omar Khayyam 

“To wisely live your life, you don't need to know muchJust remember two main rules for the beginning:You better starve, than eat whateverAnd better be alone, than with whoever.” 

Omar Khayyam

“Were a person to spend his entire life studying the wing of a mosquito, one lifetime would not suffice him even if he summoned the aid of every wise man of the East or the West.” 

Al-Jahiz

“If you think deeply about the conditions of people, you will find those who are most concerned with the faults of others to have the most faults themselves.

Al-Jahiz
