And God said that end contentment lies in me not in the materialistic world. IN QURAN Almighty Allah said that he will test human beings in this world with two parameters one is wealth and the other is offspring. He also said that sometime I will mislead human beings by providing more wealth. He also paid an argument that poor will mostly get passed in the test of wealth parameter. It is for that tricks and reason of God, we all are more attracted towards wealth and unnecessarily, we are unbalancing the globe in terms of wealth possession. This does not mean that God is condemning earning. He is advising if I bless you with wealth then do justice with others and follow our recommendation of helping others more and more and enjoy yourself. Try to achieve happiness in God's way. Because God's way is the correct way.
