﴿ قُلْ هُوَ ٱلرَّحْمَٰنُ ءَامَنَّا بِهِۦ وَعَلَيْهِ تَوَكَّلْنَا ۖ فَسَتَعْلَمُونَ مَنْ هُوَ فِى ضَلَٰلٍۢ مُّبِينٍۢ ﴾

“Say: "He is the Most Gracious: we have attained to faith in Him, and in Him have we placed our trust; and in time you will come to know which of us was lost in manifest error."”

Say) to them, O Muhammad: (He is the Beneficent) Who will save us and show mercy towards us. (In Him we believe) truly (and in Him we put our trust) and we rely on Him. (And you will soon know) when the chastisement comes down (who it is that is in error manifest) who it is that is in manifest disbelief.
