The approved opinion is that the duration of his blessed life amounted to one thousand years, of which he spent nine hundred and fifty in his mission of converting the people. He walked to the Abode of Truth [i.e. he died] during the same year in which he left the ark. The learned affirm that Nûh received his mission in the fiftieth year of his life, and that he was six hundred years old at the time of the deluge, and that he lived three hundred and fifty years more after it.
Be it known that all nations believe in the deluge except the Majûs and the inhabitants of Khatay.* Some chroniclers say that Nûh was two hundred and fifty years old when he was appointed to his mission, and that he lived nine hundred and fifty years more. According to one calculation the length of his life would amount to one thousand four hundred and fifty years. The total period of his mission [to admonish the people] before and after the deluge consisted of one thousand and two hundred years. Others state that he died at the age of one thousand and three hundred, or of one thousand four hundred and seventy years. In short, when the catastrophe of the deluge had terminated, and the company who believed in Nûh’s preaching had died, the whole world belonged to the sons of Nûh, every one of whom departed to his inheritance, and engaged in cultivating it.
