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 Messenger of Allah 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. (Using translation from Bukhārī 118)   

إِنَّ النَّاسَ يَقُولُونَ أَكْثَرَ أَبُو هُرَيْرَةَ وَاللهِ لَوْلَا آيَتَانِ فِي كِتَابِ اللهِ مَا حَدَّثْتُ حَدِيثًا ثُمَّ يَتْلُو {إِنَّ الَّذِينَ يَكْتُمُونَ مَا أَنْزَلْنَا مِنَ الْبَيِّنَاتِ وَالْهُدَى مِنْ بَعْدِ مَا بَيَّنَّاهُ لِلنَّاسِ فِي الْكِتَابِ} [البقرة 159] إِلَى {التَّوَّابُ الرَّحِيمُ} [البقرة 160] وَيَقُولُ عَلَى أَثَرِ الْآيَتَيْنِ إِنَّ إِخْوَانَنَا مِنَ الْأَنْصَارِ كَانَ يَشْغَلُهُمُ الْعَمَلُ فِي أَمْوَالِهِمْ وَإِنَّ إِخْوَانَنَا مِنَ الْمُهَاجِرِينَ كَانَ يَشْغَلُهُمُ الصَّفْقُ بِالْأَسْوَاقِ وَإِنَّ أَبَا هُرَيْرَةَ كَانَ يَلْزَمُ رَسُولَ اللهِ ﷺ لِشِبَعِ بَطْنِهِ وَيَحْضُرُ مَا لَا يَحْضُرُونَ وَيَحْفَظُ مَا لَا يَحْفَظُونَ
