صحيح مسلم

Ibn Shihab transmitted on the authority of Ibn Musayyib that Abu Huraira said: People say that Abu Huraira transmits so many ahadith, whereas Allah is the Reckoner, and they say: How is it with Muhajirs and the Ansar that they do not narrate ahadith like him (like Abu Huraira)? Abu Huraira said: I tell you that my brothers from Ansar remained busy with their lands and my brothers Muhajirs were busy in transactions in the bazars, but I always kept myself attached to Allah's Messenger (ﷺ) with bare subsistence. I remained present (in the company of the Holy Prophet), whereas they had been absent. I retained in my mind (what the Prophet (ﷺ) said), whereas they forgot it. One day Allah's Messenger (ﷺ) said: He who amongst you spreads the cloth and listens to my talk and would then press it against his chest would never forget anything heard from me. So I spread my mantle and when he had concluded his talk I then pressed it against my chest and so I never forgot after that day anything that he (the Holy Prophet) said. And if these two verses would not have been revealed in the Book I would have never transmitted anything (to anybody):" Those who conceal the clear evidence and the guidance that We revealed" (ii. 159) tip to the last verse.
