Al-Adab Al-Mufrad, Book 30, Hadith 20 (In-Book) ⓘ

'Amr ibn Shu'ayb reported via his father that his grandfather related that the Prophet, may Allah bless him and grant him peace, said, "On the Day of Rising, the proud will be gathered like specks in the form of men. Abasement will envelop them on every side. They will be driven to a prison in Jahannam called Bulas. The hottest of fires will rise over them. They will have to drink the pus of the people of the Fire, the foul fluid that their skins excrete."

حَدَّثَنَا مُحَمَّدُ بْنُ سَلاَمٍ، قَالَ‏:‏ أَخْبَرَنَا عَبْدُ اللهِ بْنُ الْمُبَارَكِ، عَنْ مُحَمَّدِ بْنِ عَجْلاَنَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ يُحْشَرُ الْمُتَكَبِّرُونَ يَوْمَ الْقِيَامَةِ أَمْثَالَ الذَّرِّ فِي صُورَةِ الرِّجَالِ، يَغْشَاهُمُ الذُّلُّ مِنْ كُلِّ مَكَانٍ، يُسَاقُونَ إِلَى سِجْنٍ مِنْ جَهَنَّمَ يُسَمَّى‏:‏ بُولَسَ، تَعْلُوهُمْ نَارُ الأَنْيَارِ، وَيُسْقَوْنَ مِنْ عُصَارَةِ أَهْلِ النَّارِ، طِينَةَ الْخَبَالِ‏.‏
