باب نُزُلِ أَهْلِ الْجَنَّةِ ‏‏
Sahih Muslim 2792

Abu al-Sa'id Khudri reported Allah's Messenger (ﷺ) as saying that the earth would turn to be one single bread on the Day of Resurrection and the Almighty would turn it in His hand as one of you turns a loaf while on a journey. It would be a feast arranged in the honour of the people of Paradise. He (the narrator) further narrated that a person from among the Jews came and he said:

Abu al-Qasim, may the Compassionate Lord be pleased with you! May I inform you about the feast arranged in honour of the people of Paradise on the Day of Resurrection? He said: Do it, of course. He said: The earth would become one single bread. Then Allah's Messenger (ﷺ) looked towards us and laughed until his molar teeth became visible. He then again said: May I inform you about that with which they would season it? He said: Do it, of course. He said: Their seasoning would be balim and fish. The Companions of the Prophet (ﷺ) said: What is this balam? He said: Ox and fish from whose excessive livers seventy thousand people would be able to eat.
حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، حَدَّثَنِي خَالِدُ بْنُ يَزِيدَ، عَنْ سَعِيدِ بْنِ أَبِي هِلاَلٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ تَكُونُ الأَرْضُ يَوْمَ الْقِيَامَةِ خُبْزَةً وَاحِدَةً يَكْفَؤُهَا الْجَبَّارُ بِيَدِهِ كَمَا يَكْفَأُ أَحَدُكُمْ خُبْزَتَهُ فِي السَّفَرِ نُزُلاً لأَهْلِ الْجَنَّةِ ‏"‏ ‏.‏ قَالَ فَأَتَى رَجُلٌ مِنَ الْيَهُودِ فَقَالَ بَارَكَ الرَّحْمَنُ عَلَيْكَ أَبَا الْقَاسِمِ أَلاَ أُخْبِرُكَ بِنُزُلِ أَهْلِ الْجَنَّةِ يَوْمَ الْقِيَامَةِ قَالَ ‏"‏ بَلَى ‏"‏ ‏.‏ قَالَ تَكُونُ الأَرْضُ خُبْزَةً وَاحِدَةً - كَمَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم - قَالَ فَنَظَرَ إِلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم ثُمَّ ضَحِكَ حَتَّى بَدَتْ نَوَاجِذُهُ قَالَ أَلاَ أُخْبِرُكَ بِإِدَامِهِمْ قَالَ ‏"‏ بَلَى ‏"‏ ‏.‏ قَالَ إِدَامُهُمْ بَالاَمُ وَنُونٌ ‏.‏ قَالُوا وَمَا هَذَا قَالَ ثَوْرٌ وَنُونٌ يَأْكُلُ مِنْ زَائِدَةِ كَبِدِهِمَا سَبْعُونَ أَلْفًا ‏.‏
