Do they not consider how many a generation We have destroyed before them, whom We had established in the earth as We have not established you, and We sent the clouds pouring rain on them in abundance, and We made the rivers to flow beneath them, then We destroyed them on account of their faults and raised up after them another generation.

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

Certainly Allah had shown to His Messenger the vision with truth: you shall most certainly enter the Sacred Mosque, if Allah pleases, in security, (some) having their heads shaved and (others) having their hair cut, you shall not fear, but He knows what you do not know, so He brought about a near victory before that.
