The man who makes his religion a means to the gaining of this world, will lose both worlds alike; whereas the man who gives up this world for the sake of religion, will get both worlds alike.

Indeed, the drunken man while in that condition does not know the definition of drunkenness nor the scientific account of it; he has not the very least scientific knowledge of it. The sober man, on the other hand, knows the definition of drunkenness and its basis, yet he is not drunk in the very least. Again the doctor, when he is himself ill, knows the definition and causes of health and the remedies which restore it, and yet is lacking in health. Similarly there is a difference between knowing the true nature and causes and conditions of the ascetic life and actually leading such a life and forsaking the world.

The proximity between the counterfeit and the good coin does not make the good coin counterfeit nor the counterfeit good. In the same way the proximity between truth and falsehood does not make truth falsehood nor falsehood truth.

The lowest degree of education is to distinguish oneself from the ignorant ordinary man. The educated man does not loathe honey even if he finds it in the surgeon's cupping-glass; he realizes that the cupping glass does not essentially alter the honey. The natural aversion from it in such a case rests on popular ignorance, arising from the fact that the cupping-glass is made only for impure blood. Men imagine that the blood is impure because it is in the cupping-glass, and are not aware that the impurity is due to a property.

Do not know the truth by the men, but know the truth, and then you will know who are truthful.

A grievous crime indeed against religion has been committed by the man who imagines that Islam is defended by the denial of the mathematical sciences.

Knowledge that is not Infallible is not certain knowledge.

There is the world for you. Beauty, true beauty, is intangible. It is in the eye of the beholder. Something that we can lose at any moment, and the more you examine it, the more illusive it becomes. True happiness is virtue, and virtue is predicated on knowledge and righteous conduct.

If man's love for himself be necessary, then his love for Him through whom, first his coming-to-be, and second, his continuance in his essential being with all his inward and outward traits, his substance and his accidents, occur must also be necessary. Whoever is so besotted by his fleshy appetites as to lack this love neglects his Lord and Creator. He possesses no authentic knowledge of Him; his gaze is limited to his cravings and to things of sense. Al-Ghazali on Love, Longing, Intimacy & Contentment.

For those endowed with insight there is in reality no object of love but God, nor does anyone but He deserve love Love, Longing, Intimacy and Contentment.

We attest that He is the Willer of all things that are, the ruler of all originated phenomena; there does not come into the visible or invisible world anything meager or plenteous, small or great, good or evil, or any advantage or disadvantage, belief or unbelief, knowledge or ignorance, success or failure, increase or decrease, obedience or disobedience, except by His will. What He wills is, and what He does not, will not; there is not a glance of the eye, nor a stray thought of the heart that is not subject to His will. He is the Creator, the Restorer, the Doer of whatsoever He wills. There is none that rescinds His command, none that supplements His decrees, none that dissuades a servant from disobeying Him, except by His help and mercy, and none has power to obey Him except by His will.

How can even the lowest mind, if he reflects at all the marvels of this earth and sky, the brilliant fashioning of plants and animals, remain blind to the fact that this wonderful world with its settled order must have a maker to design, determine and direct it?

If you believe in the future life and, instead of preparing for it, sell it in order to buy this world, then that is folly! You do not normally sell two things for one; how can you give up an endless life for a limited number of days.
