وَقَطَّعْنَٰهُمْ فِى ٱلْأَرْضِ أُمَمًۭا ۖ مِّنْهُمُ ٱلصَّٰلِحُونَ وَمِنْهُمْ دُونَ ذَٰلِكَ ۖ وَبَلَوْنَٰهُم بِٱلْحَسَنَٰتِ وَٱلسَّيِّـَٔاتِ لَعَلَّهُمْ يَرْجِعُونَ
And We have sundered them in the earth as (separate) nations. Some of them are righteous, and some far from that. And We have tried them with good things and evil things that haply they might return.
