Bismillahirrahmanirrahim

✦ *How Abu Hurairah radi Allahu anhu used to remember so many Ahadith ?*

-----------------

✦ Narrated Abu Huraira Radi Allahu Anhu I said, "O Allah's Messenger Sallallahu Alaihi wasallam I hear many narrations from you but I forget them." He said, "Spread your covering sheet." I spread my sheet and he moved both his hands as if scooping something and emptied them in the sheet and said, "Wrap it." I wrapped it round my body, and since then I have never forgotten.

Sahih Bukhari, Book 56, Hadith 841
