And We divided them into twelve tribes, as nations; and We revealed to Musa when his people asked him for water: Strike the rock with your staff, so outnowed from it twelve springs; each tribe knew its drinking place; and We made the clouds to give shade over them and We sent to them manna and quails: Eat of the good things We have given you. And they did not do Us any harm, but they did injustice to their own souls.

And Allah sets forth a parable: (Consider) a town safe and secure to which its means of subsistence come in abundance from every quarter; but it became ungrateful to Allah's favors, therefore Allah made it to taste the utmost degree of hunger and fear because of what they wrought.

And set forth to them parable of the life of this world: like water which We send down from the cloud so the herbage of the earth becomes tangled on account of it, then it becomes dry broken into pieces which the winds scatter; and Allah is the holder of power over all things.

Then We revealed to Musa: Strike the sea with your staff. So it had cloven asunder, and each part was like a huge mound.
