Quran Al-Furqan 25:37
وَقَوۡمَ نُوحٖ لَّمَّا كَذَّبُواْ ٱلرُّسُلَ أَغۡرَقۡنَٰهُمۡ وَجَعَلۡنَٰهُمۡ لِلنَّاسِ ءَايَةٗۖ وَأَعۡتَدۡنَا لِلظَّٰلِمِينَ عَذَابًا أَلِيمٗا
Translation
And the people of Noah - when they denied the messengers, We drowned them, and We made them for mankind a sign. And We have prepared for the wrongdoers a painful punishment.
