Inajulikana kwamba Abu Huraira ndiye aliyekusanya Hadithi nyingi kuliko wengine wote, na zikaandikwa pia. Imam Ibn ‘Abd al-Barr ananukuu kwa mamlaka ya Hasan ibn ‘Amr, ambaye anasema:

It is known that Abu Huraira recorded the largest collection of Ahadith, which was also documented. Imam Ibn ‘Abd al-Barr narrates on the authority of Hasan ibn ‘Amr, who says:

Nilimsimulia Abū Hurayra hadīth moja lakini alikikataa. Nikasema: "Nimeisikia hadīth hii kutoka kwako."

I narrated a hadīth to Abñ Huraira but he rejected it. I said, “I have heard this hadīth from you.”.

Alisema, "Ukiwa umesikia hadithi hii kutoka kwangu, basi lazima niiandike." Alinishika mkono na kunichukua hadi chumbani kwake. Alinionyesha maktaba yake ya vitabu vilivyokuwa na simulizi zake kutoka kwa Mtume ﷺ. Alipata hadithi niliyokuwa nimeisimulia ndani ya vitabu hivyo. Baada ya hapo, Abu Huraira alinambia, .

He said, “If you have heard this hadīth from me, then I must have it written down.” He held my hand and took me to his room. He showed me his library of books that comprised of his narrations from the Blessed Prophet (PBUH). He found the hadīth I had narrated in the books. After that, Abñ Huraira said to me, .

"Je, sikukuambia kwamba nikikusimulia hadīth yoyote, ni lazima niiandike?"35.

“Did I not tell you that if I narrated any hadīth to you I must have it written down?”35.

Hafidh ibn Hajar pia amesimulia hadith hii katika kitabu chake, Fath al-Bari, kwa mnyororo mwingine wa wasimulizi. Tukio hili linathibitisha kwamba Abu Huraira hakuandika hadithi chache tu, bali kwa kweli hadithi zote ambazo hatimaye zikawa hazina yake ya vitabu vya hadith.

Hafiz ibn Hajar has also narrated this hadīth in his book, Fatú al- Bari, with another chain. This incident proves that Abu Huraira did not document only a few aúódõth, but in fact all the ahadith which eventually became his store of hadīth books.

Hata hivyo, njia hii ya kuhifadhi haiishii hapa. Hata wanafunzi wake walikuwa wakiandika hadithi (aḥādīth) walizozisikia kutoka kwake. Mwanafunzi mmoja aliyeitwa Bashir ibn Nuhaiq aliandika:

However this method of preservation does not stop here. Even his students wrote the aúódõth they heard from him. One student named Bashir ibn Nuhaiq wrote:

Niliandika hadithi zote nilizosikia kutoka kwa Abu Huraira. Nilipoamua kuondoka, nilizisoma hadithi zote alizonisimulia mbele yake. Kisha nikauliza, "Je, hizi ndizo hadithi zote ulizonisimulia?"

I wrote down whatever aúódõth I heard from Abu Huraira. When I decided to leave, I read all the aúódõth he narrated to me by his side. Then I asked, “Are these all the aúódõth you narrated to me?”.

Akajibu, "Ndiyo."36

He replied, “Yes.”36
