Ан-Ниса 4:37

Whatever man possesses is provided by God. This reality demands that man should surrender himself to God and become His worshipper. Such a person naturally becomes humble and his humility is expressed in his relations with the other human beings interacting in his life. He behaves decently with his mother and father and feels the watchful presence of God while dealing with all those who come into contact with him. He pays everybody’s due in accordance with his relationship and need. To overlook a person, in whatever capacity he has to deal with him, appears to him as if he himself is taking the risk of being overlooked by God. One who does not surrender to God, develops an overweening sense of pride. He thinks that whatever he possesses is the outcome of his labour and intelligence. Consequently, he considers that his earnings belong to him alone. To become associated with poor relatives and destitutes becomes a matter of degradation for him. He spends lavishly to satisfy his desires and serves his own interests, but becomes mean about such expenditure as does not satisfy his ego. He is very generous in matters which give him publicity, but quite a miser in the case of unpublicized religious causes.
