فَإِن لَّمۡ تَفۡعَلُواْ وَلَن تَفۡعَلُواْ فَٱتَّقُواْ ٱلنَّارَ ٱلَّتِي وَقُودُهَا ٱلنَّاسُ وَٱلۡحِجَارَةُۖ أُعِدَّتۡ لِلۡكَٰفِرِينَ ٢٤
Fa il lam tafʿalū wa lan tafʿalū fattaqun-nāral-latī waqūduhan-nāsu wal-ḥijārah, uʿiddat lil-kāfirīn.
But if you do not - and you will never be able to - then fear the Fire, whose fuel is people and stones, prepared for the disbelievers.
