(as regards the explanation of Hadith 454). 'Indeed, it (Hell) throws about sparks (huge) as Forts.' We used to collect wood in the form of logs, three cubits long or shorter. for heating purposes in winter., and we used to call such wood, the Qasr.

"The Messenger of Allah said: 'If any one of you were to sit on a live coal until it burns his garment, that would be better for him than sitting on a grave."

When we came to the Prophet (ﷺ), each one would sit down where there was room.

The Messenger of Allah (ﷺ) said: “If one of you were to sit on a live coal that burns him, that would be better for him than if he were to sit on a grave.”
