'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."
