Abu Huraira reported Allah's Messenger ﷺ as saying: Verily, a person performs deeds for a long time like the deeds of the people of Paradise. Then his deeds are terminated like the deeds of the people of Hell and, verily, a person performs deeds like the denizens of Fire for a long time, and then this deed of his is ultimately followed by the deeds of the people of Paradise.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنِ الْعَلاَءِ، عَنْ
أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ
" إِنَّ الرَّجُلَ لَيَعْمَلُ الزَّمَنَ
الطَّوِيلَ بِعَمَلِ أَهْلِ الْجَنَّةِ ثُمَّ يُخْتَمُ لَهُ عَمَلُهُ بِعَمَلِ أَهْلِ النَّارِ وَإِنَّ الرَّجُلَ لَيَعْمَلُ الزَّمَنَ الطَّوِيلَ
بِعَمَلِ أَهْلِ النَّارِ ثُمَّ يُخْتَمُ لَهُ عَمَلُهُ بِعَمَلِ أَهْلِ الْجَنَّةِ " .
