وَمَا كَانَ لَهُۥ عَلَيْهِم مِّن سُلْطَٰنٍ إِلَّا لِنَعْلَمَ مَن يُؤْمِنُ بِٱلْءَاخِرَةِ مِمَّنْ هُوَ مِنْهَا فِى شَكٍّۢ ۗ وَرَبُّكَ عَلَىٰ كُلِّ شَىْءٍ حَفِيظٌۭ ﴿٢١﴾
And he had over them no authority except [it was decreed] that We might make evident who believes in the Hereafter from who is thereof in doubt. And your Lord, over all things, is Guardian.
