"Knowledge is better than wealth because it protects you while you have to guard wealth. It decreases if you keep on spending it but the more you make use of knowledge the more it increases. What you get through wealth dis- appears as soon as wealth disappears but what you achieve through knowledge will remain even after you."
ImamAli (a.s) Ibn e Abu Talib (a.s)
