And certainly Allah made a covenant with the Children of Israel, and We raised up among them twelve chieftains. And Allah said: Surely I am with you. If you keep up prayer and pay the poor-rate and believe in My messengers and assist them and offer to Allah a goodly gift, I will certainly cover your evil deeds, and cause you to enter Gardens wherein rivers flow. But whoever among you disbelieves after that, he indeed strays from the right way.
