باب أَدْنَى أَهْلِ الْجَنَّةِ مَنْزِلَةً فِيهَا ‏‏
Sahih Muslim 193 b

Anas reported:

The Messenger of Allah (ﷺ) said: The believers would gather on the Day of Resurrection, and they would be concerned about it, or would be made mindful of it (i. e. the trjuble for it), (and the remaining part of the hadith w, ) uld be narrated) like the one transmitted by Abu Uwana, and he said in the hadith: Then I would come for the fourth time, or I would return the fourth time, and would say: O my Lord, no one has been left but he whom the Holy Qur'an has restrained.
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَجْتَمِعُ الْمُؤْمِنُونَ يَوْمَ الْقِيَامَةِ فَيَهْتَمُّونَ بِذَلِكَ أَوْ يُلْهَمُونَ ذَلِكَ ‏"‏ ‏.‏ بِمِثْلِ حَدِيثِ أَبِي عَوَانَةَ وَقَالَ فِي الْحَدِيثِ ‏"‏ ثُمَّ آتِيهِ الرَّابِعَةَ - أَوْ أَعُودُ الرَّابِعَةَ - فَأَقُولُ يَا رَبِّ مَا بَقِيَ إِلاَّ مَنْ حَبَسَهُ الْقُرْآنُ ‏"‏ ‏.‏
