Sahih al-Bukhari 6559
Narrated Anas bin Malik:
The Prophet (ﷺ) said, "Some people will come out of the Fire after they have received a touch of the Fire, 
changing their color, and they will enter Paradise, and the people of Paradise will name them 'Al- 
Jahannamiyin' the (Hell) Fire people."
حَدَّثَنَا هُدْبَةُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ يَخْرُجُ قَوْمٌ مِنَ النَّارِ بَعْدَ مَا مَسَّهُمْ مِنْهَا سَفْعٌ، فَيَدْخُلُونَ الْجَنَّةَ، فَيُسَمِّيهِمْ أَهْلُ الْجَنَّةِ الْجَهَنَّمِيِّينَ ‏"‏‏.‏
