I encountered the hadith which relates a funny story on judgement day and the last man to enter paradise. The hadith has nothing important apart from the fact that it says, hypocrites also will enter Jannah while the Quran state it otherwise. However I noticed a part at the end of the hadith which intrigued me and I quote:
Bukhari - 008.076.577
Abu Huraira added: That man will be the last of the people of Paradiseto enter (Paradise).
Narrated 'Ata (while Abu Huraira was narrating): Abu Said was sitting in the company of Abu Huraira and he did not deny anything of his narration till he reached his saying: "All this and as much again therewith are for you." Then Abu Sa'id said, "I heard Allah's Apostle saying, 'This is for you and ten times as much.' " Abu Huraira said, "In my memory it is 'as much again therewith.' "
In this quote above, Abu Hurayrah does not seem to remember that each good deed will be rewarded by 10x (ten times) from Allah and even though his friend reminded him, he did not change his mind and still rely on his memory. He had such a good memory for hadith and he related so much of them. However, it seems that he totally missed this verse from the Quran
6:160 Whoever shall come [before God] with a good deed will gain ten times the like thereof; but whoever shall come with an evil deed will be requited with no more than the like thereof; and none shall be wronged.
The Quran is clear on this issue... So, the question is, did Abu Hurayrah memorized/know the Quran??
