Claim #6: Islam is clearer on hell than Christianity.
Of all the world’s scriptures, the Quran teaches most consistently the concept of a violent afterlife for unrepentant sinners.
Islamic teaching is definitely more gruesome than the Bible on the exact nature of hell, Sweeney’s right about that. Interestingly, a popular belief among Muslims is that Muhammad’s uncle, Abu Talib, while not a Muslim himself, was rewarded with the best place in hell for assisting his nephew during his life. His fate? Shallow fire that only goes up to his feet, making his brain boil (Sahih Bukhari, Volume 5, Book 58, Number 224).
But as far as the Quran itself is concerned, are its descriptions of hell graphic but consistent? No. Numerous verses teach that hell is eternal, but Surah 6:128 and Surah 11:106-108 both imply that hell can be temporary if Allah wills.
But setting all this aside, even if the Quran did talk more about hell than the Bible… so?
