Surah At-Tawbah (The Repentance — التوبة) (Ayah 80)

That person is a hypocrite in the eyes of God who prays to God for the blessing of wealth and when God makes him wealthy, forgets to keep aside God’s share. When a man has no wealth, he finds fault with wealthy persons, saying that they are wasting wealth in improper ways; and that if he were to be blessed with wealth by God, he would spend it on good and charitable causes. But when he receives wealth, his mentality changes. He forgets what he had said earlier and what feelings he had expressed. Now, he thinks that his wealth is the result of his own diligence and talents, which gives him the right to sole possession of it. He forgets to set aside God’s share in his wealth. Such people, in order to cover up their weaknesses, indulge in further arrogance by ridiculing those who spend their wealth for the cause of God. If a person spends more, they belittle him by calling him ostentatious, and of one who can spend only a little, in view of his circumstances, they ask derisively whether God was in need of this man’s charity. Those people who are in this way obsessed with their own greatness, are never able to see the higher realities outside themselves.
