Narrated Abu Huraira:

People say that I have narrated many Hadiths (The Prophet's narration). Had it not been for two verses in the Qur'an, I would not have narrated a single Hadith, and the verses are: "Verily those who conceal the clear sign and the guidance which We have sent down . . . (up to) Most Merciful." (2:159-160). And no doubt our Muhajir (emigrant) brothers used to be busy in the market with their business (bargains) and our Ansari brothers used to be busy with their property (agriculture). But I (Abu Huraira) used to stick to Allah's Messenger (ﷺ) contented with what will fill my stomach and I used to attend that which they used not to attend and I used to memorize that which they used not to memorize.

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ إِنَّ النَّاسَ يَقُولُونَ أَكْثَرَ أَبُو هُرَيْرَةَ، وَلَوْلاَ آيَتَانِ فِي كِتَابِ اللَّهِ مَا حَدَّثْتُ حَدِيثًا، ثُمَّ يَتْلُو ‏{‏إِنَّ الَّذِينَ يَكْتُمُونَ مَا أَنْزَلْنَا مِنَ الْبَيِّنَاتِ‏}‏ إِلَى قَوْلِهِ ‏{‏الرَّحِيمُ‏}‏ إِنَّ إِخْوَانَنَا مِنَ الْمُهَاجِرِينَ كَانَ يَشْغَلُهُمُ الصَّفْقُ بِالأَسْوَاقِ، وِإِنَّ إِخْوَانَنَا مِنَ الأَنْصَارِ كَانَ يَشْغَلُهُمُ الْعَمَلُ فِي أَمْوَالِهِمْ، وَإِنَّ أَبَا هُرَيْرَةَ كَانَ يَلْزَمُ رَسُولَ اللَّهِ صلى الله عليه وسلم بِشِبَعِ بَطْنِهِ وَيَحْضُرُ مَا لاَ يَحْضُرُونَ، وَيَحْفَظُ مَا لاَ يَحْفَظُونَ‏.‏

The Sahabah narrated the Sunnah of the Prophet (blessings and peace of Allah be upon him) to others; some of them narrated a great deal and some of them narrated only a few reports. Abu Hurayrah (may Allah be pleased with him) was one of the Sahabah who narrated the most, even though he was late in coming to Islam. Therefore some people said that Abu Hurayrah narrated the most hadith of all the Sahabah, but he was afraid that they might develop doubts about the soundness of his hadiths. Therefore he said: Were it not for these two verses – {Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture - those are cursed by Allah and cursed by those who curse, Except for those who repent and correct themselves and make evident [what they concealed]. Those - I will accept their repentance, and I am the Accepting of repentance, the Merciful} [al-Baqarah 2:159-160] – in which Allah (may He be exalted) warns the one who withholds knowledge of a curse, he would not have narrated a single hadith to them. But he was afraid that this curse might befall him if he withheld the hadith of the Messenger of Allah (blessings and peace of Allah be upon him). Then he explained the reason that helped him to memorize this great number of hadiths which no one else memorized. It was his staying close to the Prophet (blessings and peace of Allah be upon him) more than anyone else among the Sahabah. That was because the Muhajirin were preoccupied with buying and selling in the marketplaces, which kept them from staying with the Prophet (blessings and peace of Allah be upon him) and regularly attending his gatherings. The Ansar were preoccupied with working for a living in their gardens and fields. As for Abu Hurayrah (may Allah be pleased with him), he stayed close to the Messenger of Allah (blessings and peace of Allah be upon him), and was content with a little simple food every day. He attended most of the gatherings of the Prophet (blessings and peace of Allah be upon him), and he memorized from him what the others did not memorize, because he was always with the Prophet (blessings and peace of Allah be upon him). This hadith highlights the virtue of Abu Hurayrah (may Allah be pleased with him). It also points to the importance of preserving knowledge and persisting in seeking it. And it highlights the virtue of being content with little in this world, and giving precedence to seeking knowledge over seeking wealth..
