The Saheeh International Quran Translation
فَإِن لَّمْ تَفْعَلُوا۟ وَلَن تَفْعَلُوا۟ فَٱتَّقُوا۟ ٱلنَّارَ ٱلَّتِى وَقُودُهَا ٱلنَّاسُ وَٱلْحِجَارَةُ أُعِدَّتْ لِلْكَٰفِرِينَ

But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.
