Abu Ishaq reported: I was sitting with 'Abdullah bin 'Utba and there was a discussion about the age of the Messenger of Allah (ﷺ) . Some of the persons said: Abu Bakr (RA) was older than Allah's Messenger (ﷺ) . 'Abdullah said: Allah's Messenger (ﷺ) died when he was sixty-three, and Abu Bakr (RA) 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 bin Sa'd reported that Jabir had said: We were sitting with Mu'awiyah that there was a discussion about the age of Allah's Messenger (ﷺ) . Thereupon Mu'awiyah said: Allah's Messenger (ﷺ) died when he had attained the age of sixty-three, and Abu Bakr (RA) 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.
Ibn Mas'ud said: Since our acceptance of Islam and the revelation of this verse in which Allah has shown annoyance to us: "Has not the time yet come for the believers that their hearts should be humble for the remembrance of Allah?" (lvii. 16), there was a gap of four years.
