Quran 25:37 from Surah Al-Furqaan on Divine Marvels.
وَقَوۡمَ نُوحٖ لَّمَّا كَذَّبُواْ ٱلرُّسُلَ أَغۡرَقۡنَٰهُمۡ وَجَعَلۡنَٰهُمۡ لِلنَّاسِ ءَايَةٗۖ وَأَعۡتَدۡنَا لِلظَّٰلِمِينَ عَذَابًا أَلِيمٗا
English translation: And (the) people (of) Nuh when they denied the Messengers We drowned them and We made them for mankind a sign And We have prepared for the wrongdoers a punishment painful
Transliteration: waqawma nuhin lamma kadhabu al-rusula aghraqnahum waja'alnahum lilnnasi ayatan wa-a'tadna lilzzalimina adhaban aliman
