Al-Imām al-Bukhārī relates: Ahmad ibn Abī Bakr Abū Muṣ’ab narrated to us. He said: Muḥammad ibn Ibrāhīm ibn Dīnār narrated to us, from Ibn Abī Dhi’b, from Sa’īd al-Maqburī
from Abū Hurayrah (may Allāh Almighty be content with him). He said: I said: “O Messenger of Allāh, I hear many ḥadīths from you which I forget.” He said: “Spread your cloak.” So I spread my cloak. Then he gathered his two hands together (as if scooping) and placed it into my cloak, and then he said: “Wrap this cloak around your body.” So I wrapped it around my body, and after that I never forgot anything.
Al-Imām al-Bukhārī also relates: Ibrāhīm ibn al-Mundhir narrated to us. He said: Ibn Abī Fudayk narrated to us the same (ḥadīth).
حَدَّثَنَا أَحْمَدُ بْنُ أَبِي بَكْرٍ أَبُو مُصْعَبٍ قَالَ: حَدَّثَنَا مُحَمَّدُ بْنُ إِبْرَاهِيمَ بْنِ دِينَارٍ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ قَالَ
قُلْتُ يَا رَسُولَ اللهِ، إِنِّي أَسْمَعُ مِنْكَ حَدِيثًا كَثِيرًا أَنْسَاهُ. قَالَ: ابْسُطْ رِدَاءَكَ. فَبَسَطْتُهُ. قَالَ: فَغَرَفَ بِيَدَيْهِ ثُمَّ قَالَ: ضُمُّهُ. فَضَمَمْتُهُ، فَمَا نَسِيتُ شَيْئًا بَعْدَهُ.
