The Prophet ﷺ said, "The arrogant will be gathered on the Day of Resurrection like tiny ants in the form of men. Everything will tower over them in humiliation, until they are driven into a prison in Hell called Bulas, where the fire of fires will rise above them. They will be given to drink from the mire of khabal, the pus squeezed from the people of the Fire."
أن النبي ﷺ قال: يحشر المتكبرون يوم القيامة أمثال الذر في صور الناس، يعلوهم كل شيء من الصغار، حتى يدخلوا سجنا في جهنم، يقال له: بولس، فتعلوهم نار الأنيار، يسقون من طينة الخبال، عصارة أهل النار.
Tirmidhi (2492), Ahmad (6677), and Bukhari in Adab al-Mufrad (557) all narrated it through Muhammad bin Ajlan, from Amr bin Shuayb, from his father, from his grandfather, who mentioned it.Its chain is hasan because of Muhammad bin Ajlan and his teacher Amr bin Shuayb, as both of them have hasan hadith. Tirmidhi said, "This is a hasan hadith."
