وَقَوْمَ نُوحٍۢ لَّمَّا كَذَّبُوا۟ ٱلرُّسُلَ أَغْرَقْنَٰهُمْ وَجَعَلْنَٰهُمْ لِلنَّاسِ ءَايَةًۭ ۖ وَأَعْتَدْنَا لِلظَّٰلِمِينَ عَذَابًا أَلِيمًۭا
And Noah's folk, when they denied the messengers, We drowned them and made of them a portent for mankind. We have prepared a painful doom for evil-doers.
