It is well-known that Abu Huraira (RA) has narrated more Ahadith than any other companion of the Holy Prophet (SAWS). The number of Ahadith reported by him is said to be 5374. The reason was that he, after embracing Islam, devoted his full life for the sole purpose of bearing and preserving the Ahadith of the Holy Prophet (SAWS). Unlike the other famous companions, he did not employ himself in any economic activity. He used to remain in the Mosque of the Holy Prophet (SAWS) to hear what he said and to witness each event around him. He remained hungry, faced starvation and hardships. Yet, he did not leave the function he had undertaken.
There are concrete evidences that he had preserved the Ahadith in written form. One of his pupils, namely, Hasan ibn ‘Amr reports that once Abu Hurairah, took him to his home and showed him “many books” containing the Ahadith of the Holy Prophet (Bayan ul Ilm).
It shows that Abu Hurairah had many scripts of Ahadith with him. It is also established that a number of his pupils had prepared several scripts of his narrations.
