Indeed, those who disbelieve and die while they are disbelievers - never (3:91)

﴿إِنَّ الَّذِينَ كَفَرُوا وَمَاتُوا وَهُمْ كُفَّارٌ فَلَن يُقْبَلَ مِنْ أَحَدِهِم مِّلْءُ الْأَرْضِ ذَهَبًا وَلَوِ افْتَدَىٰ بِهِ ۗ أُولَٰئِكَ لَهُمْ عَذَابٌ أَلِيمٌ وَمَا لَهُم مِّن نَّاصِرِينَ﴾
[ آل عمران: 91]

3:91 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 while in disbelief will not be able to ransom themselves from receiving the punishment of Allah, even were they to try and ransom themselves with the weight of the entire earth in gold.
They will have a painful punishment, and they will have no helpers on the Day of Judgement to remove them from their suffering.

Verily, those who disbelieved, and died while they were disbelievers, the (whole) earth full of gold will not be accepted from anyone of them even if they offered it as a ransom. For them is a painful torment and they will have no helpers.

Abdullah Yusuf Ali - Translation

As to those who reject Faith, and die rejecting,- never would be accepted from any such as much gold as the earth contains, though they should offer it for ransom. For such is (in store) a penalty grievous, and they will find no helpers.

Safi-ur-Rahman al-Mubarakpuri

Verily, those who disbelieved, and died while they were disbelievers, the (whole) earth full of gold will not be accepted from anyone of them if they offered it as a ransom. For them is a painful torment and they will have no helpers.
