فَبَدَّلَ ٱلَّذِينَ ظَلَمُوا۟ مِنْهُمْ قَوْلًا غَيْرَ ٱلَّذِى قِيلَ لَهُمْ فَأَرْسَلْنَا عَلَيْهِمْ رِجْزًۭا مِّنَ ٱلسَّمَآءِ بِمَا كَانُوا۟ يَظْلِمُونَ
But those of them who did wrong changed the word which had been told them for another saying, and We sent down upon them wrath from heaven for their wrongdoing.
