'Ammar, the freed slave of Banu Hashim, reported: I asked Ibn 'Abbas how old was he when death overtook the Messenger of Allah (ﷺ) . He said: I little know that such a thing is not known to a man like you who belong to his people. He said: I asked people about it but they differed with me, and I liked to know your opinion about it. He said: Do you know counting? He said: Yes. He then said: Bear this in mind very well that he was commissioned (as a Prophet) at the age of forty, and he stayed in Makkah for fifteen years; sometime in peace and sometime in dread, and (lived) for ten years after his migration to Madinah.

Ammar, the freed slave of Banu Hashim, reported that Ibn 'Abbas said that Allah's Messenger (ﷺ) died when he had attained the age of sixty-five.

Ibn 'Abbas reported that Allah's Messenger (ﷺ) stayed in Makkah for fifteen years (after his advent as a Prophet) and he heard the voice of Gabriel (ؑ) and saw his radiance for seven years but did not see any visible form, and then received revelation for ten years, and he stayed in Madinah for ten years.
