Whoever determines the truth from people alone will remain lost in the plains of bewilderment. Rather, know the truth, and you will know its people.
Al-GhazaliO youth.......be assured that knowledge alone does not strengthen the hand......Though a man read a hundred thousand scientific questions and understood them or learned them, but did not work with them---They do not benefit him except by working.....Knowledge is the tree, and working is its fruit; and though you studied a hundred years and assembled a thousand books, you would not be prepared for the mercy of Allah the Exalted except by working.
Al-GhazaliA human-being is not a human-being while his tendencies include self-indulgence, covetousness, temper and attacking other people
Al-GhazaliDo not fix hopes on your health, and do not laugh away life. Remember how they walked and now all their joints lie separately, and the tongue with which they talked lightly is eaten away by the worms
Al-Ghazali
