On the whole, we will repeat that this Religion of Mahomet's is a kind of Christianity; has a genuine element of what is spiritually highest looking through it, not to be hidden by all its imperfections. The Scandinavian God , the god of all rude men, — this has been enlarged into a Heaven by Mahomet; but a Heaven symbolical of sacred Duty, and to be earned by faith and well-doing, by valiant action, and a divine patience which is still more valiant. It is Scandinavian Paganism, and a truly celestial element superadded to that. Call it not false; look not at the falsehood of it, look at the truth of it. For these twelve centuries, it has been the religion and life-guidance of the fifth part of the whole kindred of Mankind. Above all things, it has been a religion heartily . These Arabs believe their religion, and try to live by it! No Christians, since the early ages, or only perhaps the English Puritans in modern times, have ever stood by their Faith as the Moslem do by theirs, — believing it wholly, fronting Time with it, and Eternity with it.
Thomas Carlyle
