And assuredly Allah took a bond from the Children of Isra 'il , and We raised from amongst them twelve wardens . And Allah said : verily I am with you , if ye establish prayer and give the poor-rate and believe in My apostles and support them and lend unto Allah a goodly loan , I shall surely expiate for you your misdeeds and surely shall make you enter the Gardens whereunder rivers flow ; then whosoever of you shall disbelieve thereafter , he hath surely strayed from the level way .
