Ali 'Imran 3:91

Inna allatheena kafaroo wamatoowahum kuffarun falan yuqbala min ahadihim miloal-ardi thahaban walawi iftada bihi ola-ikalahum AAathabun aleemun wama lahum min nasireen

Indeed, those who disbelieve and die while they are disbelievers - never would the [whole] capacity of the earth in gold be accepted from one of them if he would [seek to] ransom himself with it. For those there will be a painful punishment, and they will have no helpers.

Those who disbelieve and die as disbelievers, even an Earth-full of gold shall never be accepted from any of them, even if one were to offer it as ransom. They are the ones for whom there is a painful punishment, and for them there are no helpers.
