Quran 16.94-95

“Woe upon you who dissimulate when you take an oath! You are tricksters since you teach that a man may swear by the temple and break his oath, but that whoso swears by the gold in the temple must remain bound. You are all fools and blind. You are not even consistent in your dishonesty, for which is the greater, the gold or the temple which has supposedly sanctified the gold? You also teach that, if a man swears by the altar, it is nothing; but that, if one swears by the gift that is upon the altar, then shall he be held as a debtor. Again are you blind to the truth, for which is the greater, the gift or the altar which sanctifies the gift? How can you justify such hypocrisy and dishonesty in the sight of the God of heaven?

“Some of you, before you entered the kingdom, were very shrewd in dealing with your business associates. If you were unjust and often unfair, you were nonetheless prudent and farseeing in that you transacted your business with an eye single to your present profit and future safety. Likewise should you now so order your lives in the kingdom as to provide for your present joy while you also make certain of your future enjoyment of treasures laid up in heaven. If you were so diligent in making gains for yourselves when in the service of self, why should you show less diligence in gaining souls for the kingdom since you are now servants of the brotherhood of man and stewards of God?

“Well did the Prophet Jeremiah describe many mortals when he said: ‘You are near God in the mouth but far from him in the heart.’ And have you not also read that direful warning of the prophet who said: ‘The priests thereof teach for hire, and the prophets thereof divine for money. At the same time they profess piety and proclaim that the Lord is with them.’ Have you not been well warned against those who ‘speak peace to their neighbors when mischief is in their hearts,’ those who ‘flatter with the lips while the heart is given to double-dealing’? Of all the sorrows of a trusting man, none are so terrible as to be ‘wounded in the house of a trusted friend.’”

“In your lives overthrow error and overcome evil by the love of the living truth. In all your relations with men do good for evil. The Lord God is merciful and loving; he is forgiving. Let us love God, for he first loved us. By God’s love and through his mercy we shall be saved. Poor men and rich men are brothers. God is their Father. The evil you would not have done you, do not to others.

“Woe upon all of you who reject truth and spurn mercy! Many of you are like whited sepulchres, which outwardly appear beautiful but within are full of dead men’s bones and all sorts of uncleanness. Even so do you who knowingly reject the counsel of God appear outwardly to men as holy and righteous, but inwardly your hearts are filled with hypocrisy and iniquity.

“9. The trusteeship of the wealth of one person for the benefit of others is a solemn and sacred responsibility. Do not hazard or jeopardize such a trust. Take for yourself of any trust only that which all honest men would allow.

3. You shall not bear false witness.

“No religionist may hope to attain the enlightenment of immortal wisdom who persists in being slothful, indolent, feeble, idle, shameless, and selfish. But whoso is thoughtful, prudent, reflective, fervent, and earnest — even while he yet lives on earth — may attain the supreme enlightenment of the peace and liberty of divine wisdom. Remember, every act shall receive its reward. Evil results in sorrow and sin ends in pain. Joy and happiness are the outcome of a good life. Even the evildoer enjoys a season of grace before the time of the full ripening of his evil deeds, but inevitably there must come the full harvest of evil-doing. Let no man think lightly of sin, saying in his heart: ‘The penalty of wrongdoing shall not come near me.’ What you do shall be done to you, in the judgment of wisdom. Injustice done to your fellows shall come back upon you. The creature cannot escape the destiny of his deeds.

Never, in all your ascent to Paradise, will you gain anything by impatiently attempting to circumvent the established and divine plan by short cuts, personal inventions, or other devices for improving on the way of perfection, to perfection, and for eternal perfection.

“‘Why have you fasted? For what reason do you afflict your souls while you continue to find pleasure in oppression and to take delight in injustice? Behold, you fast for the sake of strife and contention and to smite with the fist of wickedness. But you shall not fast in this way to make your voices heard on high.
