Shama-il Tirmidhi Chapter 52, Hadith Number 3 (364).
‘Aayeshah Radiyallahu ‘Anha reports: “Rasulullah Sallallahu ‘Alayhi Wasallam passed away at the age of sixty three years.
This narration is also to strengthen the previous narrations. It is confirmed from many narrations that Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam attained the age of sixty three years. Therefore the narration that are contrary to these are not correct, or are not correct in their apparent form.
