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.

He sends down water from the cloud, then watercourses flow (with water) according to their measure, and the torrent bears along the swelling foam, and from what they melt in the fire for the sake of making ornaments or apparatus arises a scum like it; thus does Allah compare truth and falsehood; then as for the scum, it passes away as a worthless thing; and as for that which profits the people, it tarries in the earth; thus does Allah set forth parables.

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.

Had We sent down this Quran on a mountain, you would certainly have seen it falling down, splitting asunder because of the fear of Allah, and We set forth these parables to men that they may reflect.
