Anas b. Malik reported that Allah's Messenger (ﷺ) died when he was sixty-three years old, and so was the case with Abu Bakr, and so was the case with Umar who was also sixty-three (when he died).

'A'isha reported that Allah's Messenger (ﷺ) died when he had attained the age of sixty-three. And a hadith like this had been transmitted on the authority of Sa'id b. Musayyib.
