Surah Saba · Ayah 21

وَمَا كَانَ لَهُۥ عَلَيْهِم مِّن سُلْطَٰنٍ إِلَّا لِنَعْلَمَ مَن يُؤْمِنُ بِٱلْءَاخِرَةِ مِمَّنْ هُوَ مِنْهَا فِى شَكٍّۢ ۗ وَرَبُّكَ عَلَىٰ كُلِّ شَىْءٍ حَفِيظٌۭ

Wa maa kaana lahoo 'alaihim min sultaanin illaa lina'lama mai yu minu bil Aakhirati mimman huwa minhaa fee shakk; wa Rabbuka 'alaa kulli shai'in Hafeez

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.
