The Messenger of Allah ﷺ passed away at the age of sixty-three.Ibn Shihab said, Saeed bin Musayab informed me of the same.
أن رسول الله ﷺ توفي وهو ابن ثلاث وستين الله سنة. وقال ابن شهاب: أخبرني سعيد بن المسيب بمثل ذلك.
Bukhari narrated it in the Book of Military Expeditions (4466), and Muslim in the Book of Virtues (2349:115), both through the route of Layth, who said, Aqeel bin Khalid told me, from Ibn Shihab, from Urwa, from Ayesha, who said, and she mentioned it.
