Men 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-GhazaliLove for God is the farthest reach of all stations, the sun of the highest degrees, and there is no station after that of love, except its fruit and its consequences.
Al-GhazaliNeglect not your time, nor use it haphazardly; on the contrary you should bring yourself to account. Structure your litanies and other practices during each day and night. This is how to bring about the spiritual blessing (baraka) in each period. If each of your breaths is a priceless jewel, Be not like the deceived fools who are joyous because each day their wealth increases while their life grows ever shorter.
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
