وَمَا كَانَ لَهُۥ عَلَيۡهِم مِّن سُلۡطَٰنٍ إِلَّا لِنَعۡلَمَ مَن يُؤۡمِنُ بِٱلۡأٓخِرَةِ مِمَّنۡ هُوَ مِنۡهَا فِي شَكّٖۗ وَرَبُّكَ عَلَىٰ كُلِّ شَيۡءٍ حَفِيظٞ

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

But he had no authority over them,- except that We might test the man who believes in the Hereafter from him who is in doubt concerning it: and thy Lord doth watch over all things.

— Saba' (سَبَأ), 34:21
