The Sovereignty
قُلْ أَرَءَيْتُمْ إِنْ أَهْلَكَنِىَ ٱللَّهُ وَمَن مَّعِىَ أَوْ رَحِمَنَا فَمَن يُجِيرُ ٱلْكَـٰفِرِينَ مِنْ عَذَابٍ أَلِيمٍ
Say, [O Muhammad], "Have you considered: whether Allah should cause my death and those with me or have mercy upon us, who can protect the disbelievers from a painful punishment?"
Nearby ayahs help place verse 67:28 in sequence and meaning.
قُلْ إِنَّمَا ٱلْعِلْمُ عِندَ ٱللَّهِ وَإِنَّمَآ أَنَا۠ نَذِيرٌ مُّبِينٌ
Say, "The knowledge is only with Allah, and I am only a clear warner."
فَلَمَّا رَأَوْهُ زُلْفَةً سِيٓـَٔتْ وُجُوهُ ٱلَّذِينَ كَفَرُوا۟ وَقِيلَ هَـٰذَا ٱلَّذِى كُنتُم بِهِۦ تَدَّعُونَ
But when they see it approaching, the faces of those who disbelieve will be distressed, and it will be said, "This is that for which you used to call."
قُلْ هُوَ ٱلرَّحْمَـٰنُ ءَامَنَّا بِهِۦ وَعَلَيْهِ تَوَكَّلْنَا ۖ فَسَتَعْلَمُونَ مَنْ هُوَ فِى ضَلَـٰلٍ مُّبِينٍ
Say, "He is the Most Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error."
قُلْ أَرَءَيْتُمْ إِنْ أَصْبَحَ مَآؤُكُمْ غَوْرًا فَمَن يَأْتِيكُم بِمَآءٍ مَّعِينٍۭ
Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?"
