Allah says:
Leave Me with the one I created alone, And to whom I granted extensive wealth, And children present [with him], And spread [everything] before him, easing [his life]. Then he desires that I should add more. No! Indeed, he has been toward Our verses obstinate. I will cover him with arduous torment. Indeed, he thought and deliberated. So may he be destroyed [for] how he deliberated. Then may he be destroyed [for] how he deliberated. Then he considered [again]; Then he frowned and scowled; Then he turned back and was arrogant, And said, "This is not but magic imitated [from others]. This is not but the word of a human being." I will drive him into Saqar! And what can make you know what is Saqar? It lets nothing remain and leaves nothing [unburned], Blackening the skins! Over it are nineteen. - 74:11-30
