Sahih Bukhari Volume 3, Book 41, Hadith 2351

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ يَقُولُونَ إِنَّ أَبَا هُرَيْرَةَ يُكْثِرُ الْحَدِيثَ‏.‏ وَاللَّهُ الْمَوْعِدُ، وَيَقُولُونَ مَا لِلْمُهَاجِرِينَ وَالأَنْصَارِ لاَ يُحَدِّثُونَ مِثْلَ أَحَادِيثِهِ وَإِنَّ إِخْوَتِي مِنَ الْمُهَاجِرِينَ كَانَ يَشْغَلُهُمُ الصَّفْقُ بِالأَسْوَاقِ، وَإِنَّ إِخْوَتِي مِنَ الأَنْصَارِ كَانَ يَشْغَلُهُمْ عَمَلُ أَمْوَالِهِمْ، وَكُنْتُ امْرَأً مِسْكِينًا أَلْزَمُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى مِلْءِ بَطْنِي، فَأَحْضُرُ حِينَ يَغِيبُونَ وَأَعِي حِينَ يَنْسَوْنَ، وَقَالَ النَّبِيُّ صلى الله عليه وسلم يَوْمًا ‏"‏ لَنْ يَبْسُطَ أَحَدٌ مِنْكُمْ ثَوْبَهُ حَتَّى أَقْضِيَ مَقَالَتِي هَذِهِ، ثُمَّ يَجْمَعَهُ إِلَى صَدْرِهِ، فَيَنْسَى مِنْ مَقَالَتِي شَيْئًا أَبَدًا ‏"‏‏.‏ فَبَسَطْتُ نَمِرَةً لَيْسَ عَلَىَّ ثَوْبٌ غَيْرَهَا، حَتَّى قَضَى النَّبِيُّ صلى الله عليه وسلم مَقَالَتَهُ، ثُمَّ جَمَعْتُهَا إِلَى صَدْرِي، فَوَالَّذِي بَعَثَهُ بِالْحَقِّ مَا نَسِيتُ مِنْ مَقَالَتِهِ تِلْكَ إِلَى يَوْمِي هَذَا، وَاللَّهِ لَوْلاَ آيَتَانِ فِي كِتَابِ اللَّهِ مَا حَدَّثْتُكُمْ شَيْئًا أَبَدًا ‏{‏إِنَّ الَّذِينَ يَكْتُمُونَ مَا أَنْزَلْنَا مِنَ الْبَيِّنَاتِ‏}‏ إِلَى قَوْلِهِ ‏{‏الرَّحِيمُ‏}‏

Narrated By Abu Huraira : The people say that Abu Huraira narrates too many narrations. In fact Allah knows whether I say the truth or not. They also ask, "Why do the emigrants and the Ansar not narrate as he does?" In fact, my emigrant brethren were busy trading in the markets, and my Ansar brethren were busy with their properties. I was a poor man keeping the company of Allah's Apostle and was satisfied with what filled my stomach. So, I used to be present while they (i.e. the emigrants and the Ansar) were absent, and I used to remember while they forgot (the Hadith). One day the Prophet said, "Whoever spreads his sheet till I finish this statement of mine and then gathers it on his chest, will never forget anything of my statement." So, I spread my covering sheet which was the only garment I had, till the Prophet finished his statement and then I gathered it over my chest. By Him Who had sent him (i.e. Allah's Apostle) with the truth, since then I did not forget even a single word of that statement of his, until this day of mine. By Allah, but for two verses in Allah's Book, I would never have related any narration (from the Prophet). (These two verses are): "Verily! Those who conceal the clear signs and the guidance which we have sent down... (up to) the Merciful.' (2.159-160)
