The Sahabah used to preserve the Sunnah of the Prophet (blessings and peace of Allah be upon him) in various ways. Some of them committed it to memory, and others wrote it down on sheets and in books. Some of them did a great deal of that and some of them did a little. In this hadith, Abu Hurayrah (may Allah be pleased with him) narrates that there was no one among the Sahabah who narrated more hadiths than him, except ‘Abdullah ibn ‘Amr (may Allah be pleased with him); he had a unique advantage over Abu Hurayrah in that he used to write down the hadith; he would write down whatever he heard. The words of Abu Hurayrah (may Allah be pleased with him) imply that ‘Abdullah ibn ‘Amr ibn al-‘As (may Allah be pleased with him) collected more hadiths than he did, even though what is narrated from him is less in number. That is for several reasons, the first of which is that ‘Abdullah ibn ‘Amr (may Allah be pleased with him) lived in Egypt, and he used to travel between Egypt and al-Ta’if to reside for some time in each place. Seekers of knowledge did not travel to those two places as they would travel to Madinah, where Abu Hurayrah (may Allah be pleased with him) lived. Abu Hurayrah was also in a position to issue fatwas and teach hadith until he died, as can be seen from the large number of people who narrated from Abu Hurayrah. It was said that eight hundred of the Tabi‘in narrated from him, which did not happen in the case of anyone else. The second reason is that ‘Abdullah ibn ‘Amr (may Allah be pleased with him) was more focused on worship than teaching, so fewer reports were narrated from him. The third reason is something that was unique to Abu Hurayrah (may Allah be pleased with him), which was that the Prophet (blessings and peace of Allah be upon him) had prayed that he would not forget what he heard from him. The fourth reason was that in Syria, ‘Abdullah (may Allah be pleased with him) had acquired a camel-load of books of the People of the Book, which he used to read and narrate from them, so many of the leading scholars among the Tabi‘in avoided learning from him. The words of Abu Hurayrah (may Allah be pleased with him) clearly state that they used to write down the hadiths of the Messenger of Allah (blessings and peace of Allah be upon him), even though he had previously forbidden them to write down the Sunnah and hadith, as Muslim narrated from Abu Sa‘id al-Khudri that the Messenger of Allah (blessings and peace of Allah be upon him) said: “Do not write down anything from me. Whoever has written down anything from me other than the Qur’an, let him erase it.” That was for fear that the Qur’an might become mixed with other things. But after the Qur’an had been memorized and become well entrenched in the hearts of the Sahabah, and there was no longer any fear of them mixing it with anything else, the Messenger of Allah (blessings and peace of Allah be upon him) gave permission to some of the Sahabah to write down hadiths. This hadith highlights the virtue of Abu Hurayrah and ‘Abdullah ibn ‘Amr ibn al-‘As (may Allah be pleased with them both). It also indicates that those of the companions of the Messenger of Allah (blessings and peace of Allah be upon him) who were literate both memorized the hadiths and wrote them down as an extra precaution. If a narrator heard a hadith but did not write it down, he relied only on what he had memorized, so his accuracy was based on only one thing, whereas the accuracy of the literate person who also wrote it down was based on two things..
