Al-Furqan 25:37

Waqawma noohin lamma kaththabooarrusula aghraqnahum wajaAAalnahum linnasiayatan waaAAtadna liththalimeenaAAathaban aleema

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.

As for the people of NūH, when they rejected the messengers, We drowned them and made them an example for mankind, and We have prepared a painful punishment for the transgressors.
