Chapter: The Eternal Delight Of The People Of Paradise, And The Verse In Which Allah Says: "And It Will Be Announced To Them: This Is The Paradise Which You Have Inherited For What You Used To Do"
(8)
بَاب فِي دَوَامِ نَعِيمِ أَهْلِ الْجَنَّةِ وَقَوْله تَعَالَى وَنُودُوا أَنْ تِلْكُمْ الْجَنَّةُ أُورِثْتُمُوهَا بِمَا كُنْتُمْ تَعْمَلُونَ

Abu Huraira reported Allah's Apostle (ﷺ) as saying:

He who would get into Paradise (would be made to enjoy such an everlasting) bliss that he would neither become destitute, nor would his clothes wear out, nor his youth would decline.
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ يَدْخُلُ الْجَنَّةَ يَنْعَمُ لاَ يَبْأَسُ لاَ تَبْلَى ثِيَابُهُ وَلاَ يَفْنَى شَبَابُهُ ‏"‏ ‏.‏
