Daghfal bin Hanzalah Sadusi Radiyallahu 'Anhu narrates: "Rasulullah Sallallahu 'Alayhi Wasallam passed away at the age of sixty five years".

Commentary
After mentioning this hadith, Imaam Tirmidhi says that Daghfal Radiyallahu 'Anhu was present in the time of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam, and was of an old age. It is not proven that he had met Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. It points he had heard this narration from another person.
