Abu Hamid al-Ghazali quotes
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.
Abu Hamid al-Ghazali
