There are mobile objects and stationary objects, but there is neither motion nor staticness. - Ibn Hazm

If science, and devoting oneself to it, had no other use than avoiding exhausting temptations, rushes of hope that give worry, and thoughts that sadden the soul, that alone should give us reasons to seek it… Kinglets have sought distraction in chess, wine, music, hunting and much else that only bring harm in this world and the other.

May God make us amongst those he allows to do good, and to practice it, and those who see the right path as none of us is without weakness; whosoever sees his weakness will forget those of others. May God make us die in the faith of Muhammad. Amen, Oh Master of the Universes.

Ask questions stubbornly, very proud men who seeing themselves right without knowing anything about the matter. This shows lack of piety, a tendency to ranting, a weak mind, and excessive vanity. [...] If you hear, or read writing (you object to), do not react with violence until you have proof that what is expressed is wrong. Do not accept that with the enthusiasm of the credulous man either until being wholly convinced of that. In both situations you blind yourself and drift away from truth… Act like a person who has no preconceived views, one ready to know and accept what is right and reject what is wrong.
