Sahih al-Bukhari, Hadith 3254 ⓘ
Narrated Abu Huraira: The Prophet said, "The first batch (of people) who will enter Paradise will be (glittering) like the full moon, and the batch next to them will be (glittering) like the most brilliant star in the sky. Their hearts will be as if the heart of a single man, for they will have neither enmity nor jealousy amongst themselves; everyone will have two wives from the houris, (who will be so beautiful, pure and transparent that) the marrow of the bones of their legs will be seen through the bones and the flesh."
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنَا مُحَمَّدُ بْنُ فُلَيْحٍ، حَدَّثَنَا أَبِي، عَنْ هِلاَلٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمْرَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم " أَوَّلُ زُمْرَةٍ تَدْخُلُ الْجَنَّةَ عَلَى صُورَةِ الْقَمَرِ لَيْلَةَ الْبَدْرِ، وَالَّذِينَ عَلَى آثَارِهِمْ كَأَحْسَنِ كَوْكَبٍ دُرِّيٍّ فِي السَّمَاءِ إِضَاءَةً، قُلُوبُهُمْ عَلَى قَلْبِ رَجُلٍ وَاحِدٍ، لاَ تَبَاغُضَ بَيْنَهُمْ وَلاَ تَحَاسُدَ، لِكُلِّ امْرِئٍ زَوْجَتَانِ مِنَ الْحُورِ الْعِينِ، يُرَى مُخُّ سُوقِهِنَّ مِنْ وَرَاءِ الْعَظْمِ وَاللَّحْمِ " .
