Did Hz. Nuh (Noah) continue the duty of prophethood after the deluge too?

Dear Brother / Sister,

The following information is included in the Quran regarding the age of Hz. Nuh:

"We (once) sent Noah to his people, and he tarried among them a thousand years less fifty: but the Deluge overwhelmed them while they (persisted in) sin. But We saved him and the companions of the Ark, and We made the (Ark) a Sign for all peoples." (al-Ankabut, 29/14-15)

According to what is understood from the verse above, Hz. Nuh lived with his nation for 950 years but it is not indicated whether this period included his whole life or his prophethood or the period up to the deluge. According to those who accept this figure as the whole life of the Prophet Nuh, he became a prophet at the age of forty, the deluge took place when he was 890 years old and he lived for sixty years after the deluge. 

According to those who regard that figure as the period before the deluge and the period of prophethood before the deluge, the age of the Prophet Nuh is much more than that. (Firuzabadi, Basa'iru dhawit-Tamyiz, Beirut, VI/30) 

According to the view of Ibn Abbas, the Prophet Nuh lived for 1780 years and was buried in a place near Masjid al-Haram. (Sabuni, an-Nubuwwa wal-Anbiya, Damascus 1985, 154)
