Almsgiving is one of the leading principles of the Mohammedan religion. It was enjoined upon the followers of the Prophet by a variety of allegories, among which is the following: "The sovereign Judge shall, at the last great day, entwine him who has not bestowed alms with a frightful serpent, whose envenomed sting shall for ever pierce the avaricious hand that never opened for the relief of the unfortunate!" {227} A BRIEF ACCOUNT OF THE RISE AND DECLINE OF THE MOHAMMEDAN EMPIRE; THE LITERATURE, SCIENCE, AND RELIGION OF THE ARABS; AND THE PRESENT CONDITION OF MOHAMMEDANISM {229} A BRIEF ACCOUNT OF THE MOHAMMEDAN EMPIRE. CHAPTER I. Extent of the Arabian Empire.--Causes which led to that extent.--Continuance of Mohammedanism.--Decay of the Empire.--What led to it.--Spain revolts and sets up a separate Caliph.--Africa.--Egypt.--Bagdad.--Fall of the House of the Abbassides. The first battle in which the Arabs tried their power against the disciplined forces of the Roman empire was the battle of Muta. Though on that occasion they were successful, the most sanguine could not have ventured to predict that, before the close of a century, their empire would become more extensive than any that had ever before existed. Yet such was the fact. It overthrew the power of the Romans, and rendered the successors of the Prophet the mightiest and most absolute sovereigns on earth. Under the last monarch of the Ommiade race, {230} the Arabian empire, excepting only an obscure part of Africa, of little account, embraced a compact territory equal to six months' march of a caravan in length and four in breadth, with innumerable tributary and dependant states. In the exercise of their power, the caliphs were fettered neither by popular rights, the votes of a senate, nor constitutional laws: the Koran was, indeed, their professed rule of action; but, inasmuch as they alone were its interpreters, their will was in all cases law. The loss of Spain to the empire was more than made up by conquests in India, Tartary, and European Turkey. Samarcand and Timbuctoo studied with equal devotion the language and religion of the Koran, and at the temple of Mecca the Moor and the Indian met as brother pilgrims. Throughout the countries west of the Tigris, the language of Arabia became the vehicle of popular intercourse; and, although in Persia, Tartary, and Hindostan the native dialects continued in common use, the Arabic was also there the sacred tongue.
