ثُمَّ بَدَّلْنَا مَكَانَ ٱلسَّيِّئَةِ ٱلْحَسَنَةَ حَتَّىٰ عَفَوا۟ وَّقَالُوا۟ قَدْ مَسَّ ءَابَآءَنَا ٱلضَّرَّآءُ وَٱلسَّرَّآءُ فَأَخَذْنَٰهُم بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ
Then changed We the evil plight for good till they grew affluent and said: Tribulation and distress did touch our fathers. Then We seized them unawares, when they perceived not.
