O 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-GhazaliThere are two kinds of Riya - Showing off-Ostentation ie pure ostentation and adulterated ostention. In pure ostentation "Riya" a man does a good deed only for worldly benefit. In Adulterated ostentation, a man does a good deed with the intention of reaping the benefits of the world as well as of the Hereafter.
Al-GhazaliDo not allow your heart to take pleasure with the praises of people, nor be saddened by their condemnation.
Al-GhazaliMen have such a good opinion of themselves, of their mental superiority and intellectual depth; they believe themselves so skilled in discerning the true from the false, the path of safety from those of error, that they should be forbidden as much as possible the perusal of philosophic writings.
Al-GhazaliIn the intricate paths of life when difficulties and hardships confront a man, and the darkness of difficulty and suffering becomes long, it is patience only that acts like a light for a Muslim, that keeps him safe from wandering here and there, and saves him from the muddy marsh of disappointment, desperation and frustration.
