فَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوا۟ ٱقْتُلُوهُ أَوْ حَرِّقُوهُ فَأَنجَىٰهُ ٱللَّهُ مِنَ ٱلنَّارِ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يُؤْمِنُونَ
But the answer of his folk was only that they said: "Kill him" or "Burn him." Then Allah saved him from the Fire. Lo! herein verily are portents for folk who believe.
