Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبي سعيد سمرة بن جندب رضي الله عنه قال: لقد كنت على عهد رسول الله صلى الله عليه وسلم غلامًا ، فكنت أحفظ عنه، فما يمنعني من القول إلا أن ههنا رجالاً أسن مني. ((متفق عليه)) .
I was a boy during the lifetime of Messenger of Allah (ﷺ), and used to commit to my memory what he said, but I do not narrate what I preserved because there were among us people who were older than me.[Al-Bukhari and Muslim].
