باب كَيْفَ الْحَشْرُ
Sahih al-Bukhari 6526

Narrated Ibn `Abbas:

The Prophet (ﷺ) stood up among us and addressed (saying) "You will be gathered, barefooted, naked, and uncircumcised (as Allah says): 'As We began the first creation, We shall repeat it..' (21.104) And the first human being to be dressed on the Day of Resurrection will be (the Prophet) Abraham Al-Khalil. Then will be brought some men of my followers who will be taken towards the left (i.e., to the Fire), and I will say: 'O Lord! My companions whereupon Allah will say: You do not know what they did after you left them. I will then say as the pious slave, Jesus said, And I was witness over them while I dwelt amongst them..........(up to) ...the All-Wise.' (5.117-118). The narrator added: Then it will be said that those people (relegated from Islam, that is) kept on turning on their heels (deserted Islam).

حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنِ الْمُغِيرَةِ بْنِ النُّعْمَانِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَامَ فِينَا النَّبِيُّ صلى الله عليه وسلم يَخْطُبُ فَقَالَ ‏"‏ إِنَّكُمْ مَحْشُورُونَ حُفَاةً عُرَاةً ‏{‏كَمَا بَدَأْنَا أَوَّلَ خَلْقٍ نُعِيدُهُ‏}‏ الآيَةَ، وَإِنَّ أَوَّلَ الْخَلاَئِقِ يُكْسَى يَوْمَ الْقِيَامَةِ إِبْرَاهِيمُ، وَإِنَّهُ سَيُجَاءُ بِرِجَالٍ مِنْ أُمَّتِي، فَيُؤْخَذُ بِهِمْ ذَاتَ الشِّمَالِ‏.‏ فَأَقُولُ يَا رَبِّ أُصَيْحَابِي‏.‏ فَيَقُولُ إِنَّكَ لاَ تَدْرِي مَا أَحْدَثُوا بَعْدَكَ‏.‏ فَأَقُولُ كَمَا قَالَ الْعَبْدُ الصَّالِحُ ‏{‏وَكُنْتُ عَلَيْهِمْ شَهِيدًا مَا دُمْتُ فِيهِمْ‏}‏ إِلَى قَوْلِهِ ‏{‏الْحَكِيمُ‏}‏ قَالَ فَيُقَالُ إِنَّهُمْ لَمْ يَزَالُوا مُرْتَدِّينَ عَلَى أَعْقَابِهِمْ ‏"‏‏.‏
