Quran 23:5 · Al-Mu'minun

In this world of God, success is for one who is a true believer, one who devotes himself fully to God and not to anybody other than God, and who leads a God-oriented life. Realisation of God is not a simple matter. It brings about a revolution in the life of a man. He becomes a worshipper of God and bows down before Him in submission. His sincerity and seriousness increase to the extent that wasting time in useless pursuits appears fatal to him. He sets aside a portion of his earnings in the name of God and with that he helps the needy. He exercises control over his sexual desires and gives free rein to them only within the limit prescribed by God for the purpose. He lives his life in this world as a responsible person and never misappropriates whatever is entrusted to him. Such a man never dishonours any pledge undertaken by him. Those who possess these qualities are the favoured subjects of God. These are the people for whom God has kept ready the ideal world, namely, the gardens of Paradise. After death they will be sent into this sublime atmosphere so that they may savour its joys forever.
