What is the origin of this strange quote attributed to Muhammad?
From “Description Of Arabia And Its Inhabitants.—Part V” by Edward Gibbon, in The History of the Decline and Fall of the Roman Empire, Volume V (1788):
> “From all sides the roving Arabs were allured to the standard of religion and plunder: the apostle sanctified the license of embracing the female captives as their wives or concubines, and the enjoyment of wealth and beauty was a feeble type of the joys of paradise prepared for the valiant martyrs of the faith. “The sword,” says Mahomet, “is the key of heaven and of hell; a drop of blood shed in the cause of God, a night spent in arms, is of more avail than two months of fasting or prayer: whosoever falls in battle, his sins are forgiven: at the day of judgment his wounds shall be resplendent as vermilion, and odoriferous as musk; and the loss of his limbs shall be supplied by the wings of angels and cherubim.” The intrepid souls of the Arabs were fired with enthusiasm: the picture of the invisible world was strongly painted on their imagination; and the death which they had always despised became an object of hope and desire.”
This quote is also found, citing Gibbon, in “The Rise, Progress, Establishment, and Decline of the Mahometan Power of Antichrist” by Henry Kitt, in History: The Interpreter of Prophecy, Volume II (1799), pp. 262-263:
> “The sword,” said he, “is the key of heaven and of hell: a drop of blood shed in the cause of God, a night spent in arms, is of more avail, than two months of fasting or prayer: whoever falls in battle, his sins are forgiven; at the day of judgment his wounds shall be resplendent as vermilion, and as odoriferous as musk: and the loss of his limbs shall be supplied by the wings of angels and of cherubim.”
