Hakeemul Ummah Hazrat Moulana Ashraf Ali Thaanwi Sahib رحمه الله has said that if one reflects, one will understand that wealth is in fact a cause for pride. Wealth is like a serpent. Whilst its appearance is attractive, it is extremely poisonous. Similar is wealth. It appears attractive and pleasurable, and a cause for comfort, but in reality, it is the root cause of all corruption and hardship. A person who is proud of his wealth is like a person who is proud of his body around which snakes are wrapped. Wealth will perish while علم (knowledge) will be enduring.
