And let not those who [greedily] withhold what Allāh has given them of His bounty ever think that it is better for them. Rather, it is worse for them. Their necks will be encircled by what they withheld on the Day of Resurrection. And to Allāh belongs the heritage of the heavens and the earth. And Allāh, of what you do, is [fully] Aware.
Indeed, those who came with falsehood are a group among you. Do not think it bad for you; rather, it is good for you. For every person among them is what [punishment] he has earned from the sin, and he who took upon himself the greater portion thereof - for him is a great punishment [i.e., Hellfire].
