Abu Hurairah أبو هريرة () certainly is a sahabi on which there's a big dispute among the Muslim scholars in first place the shi'a and sunni scholars.
One of the main issues is the fact that this man who seemingly only lived at maximum three years with the prophet () was able to narrate (or better transmit) the major amount of narrations which reach according to some scholars 5374 hadith (this count includes repetitions, sahih and non-sahih narrations). Followd by 'Abdullah ibn 'Umar () with 2630 hadith, Anas ibn Malik () with 2286 hadith, 'Aishah, 'Abdullah ibn 'Abbas, Jabir ibn 'Abdullah and abu Sa'id al-Khudry (see on wikipedia here in Arabic). The scholar ibn Amin says actually among these 5374 hadith only 8 ahadith in the 9 most known sunni hadith collections (the 2 Sahihs, al-Muawtta', the Sunan's of abu Dawod, ibn Majah, an-Nasa-i, Jami' at-Tirmidhi and the Musnad's of Ahmad and ad-Darimi) are exclusively narrated by abu Hurairah (see here in Arabic).
- I'm curious whether there is an explanation defending (this amount) and meanwhile explaining how abu Hurairah managed to narrate at least twice as much as any of the sahabah ()?
I wonder if the explanation could be that he used to ask other sahabah and narrate from them.
I also read that he used to consult the former Jew Ka'ab al-Ahbar and we know that narrating from the people of the book is not per se haram based on:
The Prophet (ﷺ) said, "Convey (my teachings) to the people even if it were a single sentence, and tell others the stories of Bani Israel (which have been taught to you), for it is not sinful to do so. And whoever tells a lie on me intentionally, will surely take his place in the (Hell) Fire." (Sahih al-Bukhari)
It would be nice if these points could also be addressed in an answer.
