Hudhaifa reported that Allah's Messenger (ﷺ) stood before us one day and he did not leave anything unsaid (that he had to say) at that very spot which would happen (in the shape of turmoil) up to the Last Hour. Those who had to remember them preserved them in their minds and those who could not remember them forgot them. My friends knew them and there are certain things which slip out of my mind, but I recapitulate them when anyone makes a mention of them just as a person is lost from one's mind but is recalled to him on seeing his face.
وَحَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ عُثْمَانُ حَدَّثَنَا وَقَالَ، إِسْحَاقُ أَخْبَرَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ حُذَيْفَةَ، قَالَ قَامَ فِينَا رَسُولُ اللَّهِ صلى الله عليه وسلم مَقَامًا مَا تَرَكَ شَيْئًا يَكُونُ فِي مَقَامِهِ ذَلِكَ إِلَى قِيَامِ السَّاعَةِ إِلاَّ حَدَّثَ بِهِ حَفِظَهُ مَنْ حَفِظَهُ وَنَسِيَهُ مَنْ نَسِيَهُ قَدْ عَلِمَهُ أَصْحَابِي هَؤُلاَءِ وَإِنَّهُ لَيَكُونُ مِنْهُ الشَّىْءُ قَدْ نَسِيتُهُ فَأَرَاهُ فَأَذْكُرُهُ كَمَا يَذْكُرُ الرَّجُلُ وَجْهَ الرَّجُلِ إِذَا غَابَ عَنْهُ ثُمَّ إِذَا رَآهُ عَرَفَهُ .
