باب الدَّلِيلِ عَلَى دُخُولِ طَوَائِفَ مِنَ الْمُسْلِمِينَ الْجَنَّةَ بِغَيْرِ حِسَابٍ وَلاَ عَذَابٍ ‏‏

It is narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) said:

Seventy thousand (persons) of my Ummah would enter Paradise without rendering an account. Upon this a person said: Messenger of Allah. pray to Allah that He make me one of them. He (the Holy Prophet) said: O Allah! make him one of them. Then another stood up and said: Messenger of Allah, pray to Allah that He make me one of them. He (the Holy Prophet) said: 'Ukkasha has preceded you in this matter.
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَلاَّمِ بْنِ عُبَيْدِ اللَّهِ الْجُمَحِيُّ، حَدَّثَنَا الرَّبِيعُ، - يَعْنِي ابْنَ مُسْلِمٍ - عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ يَدْخُلُ مِنْ أُمَّتِي الْجَنَّةَ سَبْعُونَ أَلْفًا بِغَيْرِ حِسَابٍ ‏"‏ ‏.‏ فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ ‏.‏ قَالَ ‏"‏ اللَّهُمَّ اجْعَلْهُ مِنْهُمْ ‏"‏ ‏.‏ ثُمَّ قَامَ آخَرُ فَقَالَ يَا رَسُولَ اللَّهِ ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ ‏.‏ قَالَ ‏"‏ سَبَقَكَ بِهَا عُكَّاشَةُ ‏"‏ ‏.‏
