3. Ali Imran · verses 90–91

إِنَّ ٱلَّذِينَ كَفَرُواْ بَعۡدَ إِيمَٰنِهِمۡ ثُمَّ ٱزۡدَادُواْ كُفۡرٗا لَّن تُقۡبَلَ تَوۡبَتُهُمۡ وَأُوْلَٰٓئِكَ هُمُ ٱلضَّآلُّونَ

Inna allatheena kafaroo baAAda eemanihim thumma izdadoo kufran lan tuqbala tawbatuhum waolaika humu alddalloona

But those who reject Faith after they accepted it, and then go on adding to their defiance of Faith,- never will their repentance be accepted; for they are those who have (of set purpose) gone astray.

إِنَّ ٱلَّذِينَ كَفَرُواْ وَمَاتُواْ وَهُمۡ كُفَّارٞ فَلَن يُقۡبَلَ مِنۡ أَحَدِهِم مِّلۡءُ ٱلۡأَرۡضِ ذَهَبٗا وَلَوِ ٱفۡتَدَىٰ بِهِۦٓۗ أُوْلَٰٓئِكَ لَهُمۡ عَذَابٌ أَلِيمٞ وَمَا لَهُم مِّن نَّٰصِرِينَ

Inna allatheena kafaroo wamatoo wahum kuffarun falan yuqbala min ahadihim milo alardi thahaban walawi iftada bihi olaika lahum AAathabun aleemun wama lahum min nasireena

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.
