Narrated Abu Huraira: People say that I have narrated many Hadiths (The Prophet's narration). Had it not been for two verses in the Qur'an, I would not have narrated a single Hadith, and the verses are: "Verily those who conceal the clear sign and the guidance which We have sent down . . . (up to) Most Merciful." (2:159-160). And no doubt our Muhajir (emigrant) brothers used to be busy in the market with their business (bargains) and our Ansari brothers used to be busy with their property (agriculture). But I (Abu Huraira) used to stick to Allah's Apostle contented with what will fill my stomach and I used to attend that which they used not to attend and I used to memorize that which they used not to memorize.

Narrated Abu Huraira: I said to Allah's Apostle "I hear many narrations (Hadiths) from you but I forget them." Allah's Apostle said, "Spread your Rida' (garment)." I did accordingly and then he moved his hands as if filling them with something (and emptied them in my Rida') and then said, "Take and wrap this sheet over your body." I did it and after that I never forgot any thing. Narrated Ibrahim bin Al-Mundhir: Ibn Abi Fudaik narrated the same as above (Hadith...119) but added that the Prophet had moved his hands as if filling them with something and then he emptied them in the Rida' of Abu Huraira.

Narrated Abu Huraira: I have memorized two kinds of knowledge from Allah's Apostle . I have propagated one of them to you and if I propagated the second, then my pharynx (throat) would be cut (i.e. killed).
