Sahih al-Bukhari, Hadith 7450 ⓘ
Narrated Anas: The Prophet 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).
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم 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 صلى الله عليه وسلم.
