Allah is he Who sends forth the winds so they raise a cloud, then He spreads it forth in the sky as He pleases, and He breaks it up so that you see the rain coming forth from inside it; then when He causes it to fall upon whom He pleases of His servants, lo! they are joyful

Have they not travelled in the land and seen how was the end of those before them while they were stronger than these in power? And Allah is not such that any thing in the heavens or in the earth should escape Him; surely He is Knowing, Powerful.
