Sahih al-Bukhari, Hadith 118 ⓘ

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 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.‏
