Al-An'am 6:165

وَهُوَ ٱلَّذِى جَعَلَكُمْ خَلَـٰٓئِفَ ٱلْأَرْضِ وَرَفَعَ بَعْضَكُمْ فَوْقَ بَعْضٍ دَرَجَـٰتٍ لِّيَبْلُوَكُمْ فِى مَآ ءَاتَىٰكُمْ ۗ إِنَّ رَبَّكَ سَرِيعُ ٱلْعِقَابِ وَإِنَّهُۥ لَغَفُورٌ رَّحِيمٌۢ

Wahuwa alladhī jaʿalakum khalāifa l-arḍi warafaʿa baʿḍakum fawqa baʿḍin darajātin liyabluwakum fī mā ātākum inna rabbaka sarīʿu l-ʿiqābi wa-innahu laghafūrun raḥīmun

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.
