Holy Quran » HUUD : 121 - 123

And say to those who do not believe, "Work according to your position; indeed, we are working.

And wait, indeed, we are waiting."

And to Allah belong the unseen [aspects] of the heavens and the earth and to Him will be returned the matter, all of it, so worship Him and rely upon Him. And your Lord is not unaware of that which you do.
