البراء بن عازب
Al-Bara' ibn Azib RA was a Companion of the Ansar who was a boy when the Prophet ﷺ arrived in Madinah and grew up to narrate many hadiths, including eyewitness descriptions of the city's welcome and of the Prophet ﷺ himself, whom he said he had never seen anything more beautiful than. Sent home as underage from Badr, he fought at Uhud, and at the Trench he saw the Prophet ﷺ covered in dust carrying earth and chanting with the Companions.
