Al-An'am 6:165

وَهُوَ ٱلَّذِي جَعَلَكُمۡ خَلَـٰٓئِفَ ٱلۡأَرۡضِ وَرَفَعَ بَعۡضَكُمۡ فَوۡقَ بَعۡضٖ دَرَجَٰتٖ لِّيَبۡلُوَكُمۡ فِي مَآ ءَاتَىٰكُمۡۗ إِنَّ رَبَّكَ سَرِيعُ ٱلۡعِقَابِ وَإِنَّهُۥ لَغَفُورٞ رَّحِيمُۢ 165

And it is He who has made you successors upon the earth and has raised some of you above others in degrees [of rank] that He may try you through what He has given you. Indeed, your Lord is swift in penalty; but indeed, He is Forgiving and Merciful
