Sahih Muslim , Book 40, Hadith 6788 (USC-MSA) ⓘ
Sahl b. Sa'd reported Allah's Messenger as saying: The inmates of Paradise will look to the upper apartment of Paradise as you see the planets in the sky. I narrated this hadith to Nu'man b. Abi 'Ayyash and he said: I heard Abu Sa'id al-Khudri as saying: As you see the shining planets in the eastern and western (sides of) horizon.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِيَّ - عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ أَهْلَ الْجَنَّةِ لَيَتَرَاءَوْنَ الْغُرْفَةَ فِي الْجَنَّةِ كَمَا تَرَاءَوْنَ الْكَوْكَبَ فِي السَّمَاءِ " . قَالَ فَحَدَّثْتُ بِذَلِكَ النُّعْمَانَ بْنَ أَبِي عَيَّاشٍ، فَقَالَ سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ، يَقُولُ كَمَا تَرَاءَوْنَ الْكَوْكَبَ الدُّرِّيَّ فِي الأُفُقِ الشَّرْقِيِّ أَوِ الْغَرْبِيِّ " .
