And if their turning away is hard on you, then if you can seek an opening (to go down) into the earth or a ladder (to ascend up) to heaven so that you should bring them a sign and if Allah had pleased He would certainly have gathered them all on guidance, therefore be not of the ignorant.

And if We had pleased, We would certainly have exalted him thereby; but he clung to the earth and followed his low desire, so his parable is as the parable of the dog; if you attack him he lolls out his tongue; and if you leave him alone he lolls out his tongue; this is the parable of the people who reject Our communications; therefore relate the narrative that they may reflect.

Do they not then consider what is before them and what is behind them of the heaven and the earth? If We please We will make them disappear in the land or bring down upon them a portion from the heaven; most surely there is a sign in this for every servant turning (to Allah).

And among His signs is this, that you see the earth still, but when We send down on it the water, it stirs and swells: most surely He Who gives it life is the Giver of life to the dead; surely He has power over all things.

And one of His signs is the creation of the heavens and the earth and what He has spread forth in both of them of living beings; and when He pleases He is all-powerful to gather them together.
