Surah Al-Furqan, ayah 37

25:37

وَقَوۡمَ نُوحٖ لَّمَّا كَذَّبُواْ ٱلرُّسُلَ أَغۡرَقۡنَٰهُمۡ وَجَعَلۡنَٰهُمۡ لِلنَّاسِ ءَايَةٗۖ وَأَعۡتَدۡنَا لِلظَّٰلِمِينَ عَذَابًا أَلِيمٗا ٣٧

Waqawma nūhil lammā kaddhabur-rusula aghraqnāhum waja'alnāhum lin-nāsi āyatan wa a'tadnā liz-zālimīna 'adhāban alīmā

And the people of Noah - when they denied the messengers,1024 We drowned them, and We made them for mankind a sign. And We have prepared for the wrongdoers a painful punishment.

Footnotes

1024 Their denial of Noah was as if they had denied all those who brought the same message from Allāh.
