ثُمَّ أَرْسَلْنَا رُسُلَنَا تَتْرَا ۖ كُلَّ مَا جَآءَ أُمَّةًۭ رَّسُولُهَا كَذَّبُوهُ ۚ فَأَتْبَعْنَا بَعْضَهُم بَعْضًۭا وَجَعَلْنَٰهُمْ أَحَادِيثَ ۚ فَبُعْدًۭا لِّقَوْمٍۢ لَّا يُؤْمِنُونَ
Then We sent our messengers one after another. Whenever its messenger came unto a nation they denied him; so We caused them to follow one another (to disaster) and We made them bywords. A far removal for folk who believe not!
