Not in English, other languages, for the English translation I've used the online sites, there are more translations available at once, I've linked that already, Pickthall is included in the results, maybe he uses the "doom" word more than others? Anyway, thanks to the online sources, the Arabic words seem to be "عذاب" and "الْحَرِيق" Yay, Unicode! For more statistics (e.g. how often exactly the "fire" is used, how often "hell") I suggest using the local copies of the texts.
