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