258-Imam Ali Ibn Abu Talib (PBUH) says: O Kumayl! Knowledge is better than wealth. Knowledge guards you, while you have to guard the wealth. Wealth decreases by spending, while knowledge multiplies by spending, and the results of wealth die as wealth decays. O Kumayl! Those who amass wealth are dead even though they may be living, while those endowed with knowledge will remain as long as the world exists. Their bodies are not available but their figures exist in the hearts.
