صحيح البخاري

Narrated Al-A'raj:

Abu Huraira said, "You people claim that Abu Huraira narrates many narrations of Allah's Messenger. (Anyhow) with Allah will be our appointment. I was a poor man, and used to stick to Allah's Messenger (ﷺ) contented with what will fill my stomach, and the Muhajirin (emigrants) used to be busy trading in the markets, and the Ansar used to be busy looking after their properties. One-day I heard Allah's Messenger (ﷺ) saying, 'Who will spread his Rida' (a garment covering the upper part of the body) till I finished my speech and then fold it, (i.e. wrap it over your body), in which case he will never forget anything he had heard from me." So I spread my garment which I was wearing; and by Him Who sent Muhammad with the Truth, ever since, I have never forgotten whatever I heard from him (the Prophet)" (See, Hadith No. 119, Vol. 1)
