Translation:

37. And the people of Noah when they rejected the apostles We drowned them and We made them as a Sign for mankind; and We have prepared for (all) wrongdoers a grievous Penalty

Notes (Tafseer)

3093. The stories of Noah, of the prophets of 'Ad and Thamud (and of other prophets), in the reactions of their communities to their teaching are told in xxvi. 105-159, below. Here they are just mentioned to illustrate how little respect past ages had for their prophets and teachers of Truth. But Allah's Truth did not suffer: it was the blind rejecters of spiritual Truth who were wiped out.
