He told his companions that in his vision two strangers came to him and
said, "Come with us". So he went with them until they reached a man lying
on his back. As they watched another man threw a stone at the other man's
head, then, as the stone rolled away, he ran after it, picked it up and
returned to strike the man on his head again. The same thing happened
over and over again whereupon our beloved Prophet, praise and peace be
upon him, exclaimed, "Exalted is Allah! Who is this?" But his companions
just said, "Proceed, proceed."

Next, the Prophet, praise and peace be upon him, and his companions
came across another man who was also laying on his back, but this time a
man stood over him with an iron hook which he used to beat and tear open
the man's face and neck. After each beating the man's face recovered, and
he was punished over and over again. The Prophet exclaimed, "Exalted is
Allah! Who is this?" But his companions just said, "Proceed, proceed."

As they journeyed, the Prophet, praise and peace be upon him, and his
companions came across a pit-like oven in which fearsome flames leapt.
