Fakhr al-Din al-Razi

"I regret the time I have been eating instead of being in pursuit of learning - for time is precious."

"My heart was never deprived of science, There are little of the mysteries that I did not understand. For 72 years I thought night and day, Yet I came to know that nothing is to be known.”"

"It is established by evidence that there exists beyond the world a void without a terminal limit (khala' la nihayata laha), and it is established as well by evidence that God Most High has power over all contingent beings (al-mumkinat ). Therefore He the Most High has the power (qadir ) to create a thousand thousand worlds (alfa alfi 'awalim) beyond this world such that each one of those worlds be bigger and more massive than this world as well as having the like of what this world has of the throne (al-arsh), the chair (al-kursiyy), the heavens (al-samawat ) and the earth (al-ard ), and the sun (al-shams) and the moon (al-qamar ). The arguments of the philosophers (dala'il al-falasifah) for establishing that the world is one are weak, flimsy arguments founded upon feeble premises."
