Al An’am Ayah 165

وَهُوَ ٱلَّذِى جَعَلَكُمْ خَلَـٰٓئِفَ ٱلْأَرْضِ وَرَفَعَ بَعْضَكُمْ فَوْقَ بَعْضٍ دَرَجَـٰتٍ لِّيَبْلُوَكُمْ فِى مَآ ءَاتَـٰكُمْ‌ۗ إِنَّ رَبَّكَ سَرِيعُ ٱلْعِقَابِ وَإِنَّهُۥ لَغَفُورٌ رَّحِيمُۢ ١٦٥ He is the One Who has placed you as successors on earth and elevated some of you in rank over others, so He may test you with what He has given you. Surely your Lord is swift in punishment, but He is certainly All-Forgiving, Most Merciful.
