What does the Qur'an say about the age of Prophet Nuh?

On Wikipedia, it says: > The influence of Noah's preaching and prophet-hood spanned 950 years according to Quran. -- Noah in Islam I've seen this claim before, but I don't recall it being in the Qur'an. The reference it gives just says the exact same claim, without pinpointing where in the Qur'an. I didn't find it in Qur'an 71 (Surah Nuh), and Islam Q&A seems to contradict the precise claim on Wikipedia. **Question**: What does the Qur'an say about the age of Prophet Nuh?
