25:21Those who do not expect to meet Us say, “If only the angels were sent down to us, or we could see our Lord.” They have grown arrogant within themselves, and have become excessively defiant.

25:45Do you not see how your Lord extends the shadow? Had He willed, He could have made it still. And We made the sun a pointer to it.

25:51Had We willed, We could have sent to every town a warner.
