Shama-il Tirmidhi Chapter 052, Hadith Number 002 (363).

Mu'aa-wiyah Radiyallahu 'Anhu once said this in the khutbah: "Rasulullah Sallallahu 'Alayhi Wasallam passed away at the age of sixty three. (The Shaykhayn, i.e.) Abubakr Radiyallahu 'Anhu and 'Umar Radiyallahu 'Anhu also passed away at the age of sixty three years. My age (at the moment) is also sixty three".

Commentary
It means that it is not impossible for me to be blessed with the following of this natural age. The muhadditheen write that this wish of Sayyidina' Mu'aa-wiyah Radiyallahu 'Anhu was not fulfilled. He passed away at the age of eighty years. Sayyidina 'Uthmaan Radiyallahu'Anhu was not mentioned here, although he had close ties with him. The reason is apparent, that the age of 'Uthmaan Radiyallahu 'Anhu was more than eighty years old when he was martyred. The reason for Imaam Tirmidhi mentioning this narration is to strengthen the previous narration, where it is stated that Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam passed away at the age of sixty three years. The Shaykhayn were blessed with the natural following of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam in this matter.
