God took compact with the Children of Israel; and We raised up from among them twelve chieftains. And God said, 'I am with you. Surely, if you perform the prayer, and pay the alms, and believe in My Messengers and succour them, and lend to God a good loan, I will acquit you of your evil deeds, and I will admit you to gardens underneath which rivers flow. So whosoever of you thereafter disbelieves, surely he has gone astray from the right way.
