Abu Ishaq reported:I was sitting with 'Abdullah b. 'Utba and there was a discussion about the age of the Messenger of Allah (ﷺ). Some of the persons said: Abu Bakr was older than Allah's Messenger (ﷺ). 'Abdullah said: Allah's Messenger (ﷺ) died when he was sixty-three, and Abu Bakr died when he was sixty-three and so 'Umar fell as a martyr when he was sixty-three. A person from the people who was called 'Amir b. Sa'd reported that Jabir had said: We were sitting with Mu'awiya that there was a discussion about the age of Allah's Messenger (ﷺ). Thereupon Mu'awiya said: Allah's Messenger (ﷺ) died when he had attained the age of sixty-three, and Abu Bakr died when he had attained the age of sixty-three, and Umar fell as a martyr when he had attained the age of sixty-three

Jabir reported that he heard Mu'awiya say in his address that Allah's Messenger (ﷺ) died at the age of sixty-three, so was the case with Abu Bakr and 'Umar, and I (am now) sixty-three
