Sahih Muslim , Hadith 217 ⓘ
Abu Huraira reported: The Messenger of Allah said: Seventy thousand (persons) would enter Paradise as one group and among them (there would be people) whom faces would be bright like the moon.
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي حَيْوَةُ، قَالَ حَدَّثَنِي أَبُو يُونُسَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " يَدْخُلُ الْجَنَّةَ مِنْ أُمَّتِي سَبْعُونَ أَلْفًا زُمْرَةٌ وَاحِدَةٌ مِنْهُمْ عَلَى صُورَةِ الْقَمَرِ " .
