The Prophet ﷺ said, "Some people will be scorched by Hell (Fire) as a punishment for sins they have committed, and then Allah will admit them into Paradise by the grant of His Mercy. These people will be called, 'Al-Jahannamiyyin' (the people of Hell).
عَنِ النَّبِيِّ ﷺ قَالَ لَيُصِيبَنَّ أَقْوَامًا سَفْعٌ مِنَ النَّارِ بِذُنُوبٍ أَصَابُوهَا عُقُوبَةً ثُمَّ يُدْخِلُهُمُ اللَّهُ الْجَنَّةَ بِفَضْلِ رَحْمَتِهِ يُقَالُ لَهُمُ الْجَهَنَّمِيُّونَ وَقَالَ هَمَّامٌ حَدَّثَنَا قَتَادَةٌ حَدَّثَنَا أَنَسٌ عَنِ النَّبِيِّ ﷺ
