وَهُوَ الَّذي جَعَلَكُم خَلائِفَ الأَرضِ وَرَفَعَ بَعضَكُم فَوقَ بَعضٍ دَرَجاتٍ لِيَبلُوَكُم في ما آتاكُم ۗ إِنَّ رَبَّكَ سَريعُ العِقابِ وَإِنَّهُ لَغَفورٌ رَحيمٌ

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.
