Anas pia aliandika mkusanyiko wake wa hadith. Sa‘id ibn Hilal anasema katika Mustadrak ya Hakim:

Anas also wrote down his collection of ahadith. Sa‘id ibn Hilal says in the Mustadrak of Hakim:

Tulipouliza maswali mengi, Anas alitoa mfuko mkubwa, akaufungua na kusema, "Hizi ni hadithi nilizozisikia kutoka kwa Mtume aliyebarikiwa ﷺ. Niliziandika na tayari nimeshamwonyesha Mtume aliyebarikiwa ﷺ."37

When we asked a lot of questions, Anas pulled out a big bag, opened it and would say, “These are the ahadith that I have heard from the Blessed Prophet (PBUH). I wrote them down and have already shown them to the Blessed Prophet (PBUH).”37

Muhtasari wa utangulizi huu ni kwamba Allah (SWT) aliumba baadhi ya zana, kama kumbukumbu ya kuona vitu kama picha ya Waarabu, ili kuhifadhi Hadithi. Kisha akaipa maarifa haya umbo la vitendo kupitia maisha ya Masahaba ili kuilinda isigeuke kuwa falsafa nyingine. Uhifadhi huu ulipatikana kwa njia ya kanuni ya vitendo. Baadaye akawaleta wanachuoni na wanafunzi wao, ambao walijitolea maisha yao kuandika Hadithi hizi. Kisha ikafika wakati ambapo wanachuoni mia kadhaa walikusanya Hadithi zote na kuziweka katika umbo la kitabu. Tutajadili hatua hii ya mwisho katika sehemu zijazo za kitabu hiki.

The summary of this introduction is that Allah (SWTH) created certain tools, like the photographic memories of the Arabs, to help preserve the ahadith. He then gave this knowledge a practical shape through the lives of the Sahaba to protect it from becoming another philosophy. This preservation came by way of the principle of practice. Then He produced the scholars and their students, who dedicated their lives to documenting these aúódõth. Then a time came when hundreds of scholars compiled all of the ahadith and put them in book form. We will discuss this last stage in the later sections of this book.
