The Evidence that groups of Muslims will enter Paradise without being called to account, and without being punished
Sahih Muslim
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 " .
Abu Huraira reported: The Messenger of Allah (ﷺ) 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.
