وَهُوَ ٱلَّذِي جَعَلَكُمۡ خَلَٰٓئِفَ ٱلۡأَرۡضِ وَرَفَعَ بَعۡضَكُمۡ فَوۡقَ بَعۡضٖ دَرَجَٰتٖ لِّيَبۡلُوَكُمۡ فِي مَآ ءَاتَىٰكُمۡۗ إِنَّ رَبَّكَ سَرِيعُ ٱلۡعِقَابِ وَإِنَّهُۥ لَغَفُورٞ رَّحِيمُۢ ١٦٥
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.
Translation: Saheeh International (English)
Each word's meaning and sound
Allah is the One Who made you successors of those whom came before you on earth, so that you inhabit it after them. He has raised some of you in rank over others – in terms of physical form, livelihood and other aspects – in order to test you through what He has given you. Your Lord, O Messenger, is quick in delivering justice, since anything that is approaching is close. And He is also Forgiving and Compassionate towards those of His servants who repent to Him.
