“In one of his traditional sermons transmitted by his disciples, is the following apologue on the subject of charity : " When God created the earth it shook and trembled, until he put mountains upon it, to make it firm. Then the angels asked, ' O God, is there anything of thy creation stronger than these mountains ? ' And God replied, ' Iron is stronger than the mountains ; for it breaks them.' 'And is there anything of thy creation stronger than iron ? ' ' Yes ; fire is stronger than iron, for it melts it.' 'Is there anything of thy creation stronger than fire?' 'Yes; water, for it quenches fire.' ' O Lord, is there anything of thy creation stronger than water ? ' ' Yes, wind ; for it overcomes water and puts it in motion.' 'O, our Sustainer ! is there anything of thy creation stronger than wind ? ' ' Yes, a good man giving alms ; if he give with his right hand and conceal it from his left, he overcomes all things.' ”
