Surely Allah took a covenant with the Children of Israel, and We raised up from them twelve of their leaders, and Allah said: 'Behold, I am with you; if you establish Prayer and pay Zakah and believe in My Prophets and help them, and lend Allah a good loan, I will certainly efface from you your evil deeds, and will surely cause you to enter the Gardens beneath which rivers flow. Whosoever of you disbelieves thereafter has indeed gone astray from the right way.
