A comparative study of the niceties of Mussulman doctrine, and hair-breadth distinctions with those of more refined and enlightened creeds, while it displays many and striking similarities, only illustrates, with startling vividness, the time worn maxim, that "there is nothing new under the sun." CHAPTER V. DIN OR PRACTICE OF RELIGION. The Din, or Practice of Religion, comprises ablution, prayer, alms, fasting, and a pilgrimage to Mecca. Ablution.--Bathing, and various forms of ablutions, were practised long before the time of Mohammed; but he has incorporated cleanliness with his religion, until his followers seem to regard water as not only possessed of virtue to cleanse the pollutions of their bodies, but as purifying their souls from the contamination of sin. Therefore, fountains are always to be found in the neighborhood of all the mosques, in every part of the city and its suburbs, and on the highways--for they never omit this preliminary to their devotions, which includes washing the face, hands, and feet; and when they happen to be in the desert, where no water can be obtained, sand is substituted. Indeed, the same ablutions are so essential, that their observance is invariably required of the faithful, before the administration of an oath. Prayers. Five times a day the Mussulmans are summoned to prayer by the muezzin. Early in the morning, just before the sun is above the horizon, the ezan resounds through the still atmosphere, from the airy balcony of the tapering Minaré. The Muezzin, covering his ears with his hands, as if to exclude all terrestrial sound, turns his face towards Mecca, and chants with musical cadence, the beautiful Arabic formula. "Allah, ikber! Allah ikber! &c, great God! great God! there is no God, but God! I attest that Mohammed is the apostle of God! Oh, Great Redeemer! Oh! Ruler of the universe! great God! great God! there is no God but God!" and he slowly moves round the balcony, as if addressing the inhabitants of all parts of the world. Those who catch the echoes of the holy call, exclaim with solemn earnestness, "There is no power, no strength but in God Almighty." Again, when the hour of noon seems to indicate a moment of repose to the work-day world, the ezan summons all thoughts and aspirations to the great God. At three o'clock in the afternoon, at sunset, and finally at nine o'clock, the call resounds ere they prepare for sleep. How beautiful thus to note the passage of time, to look thus from earth to heaven, to forget for a moment all worldly cares, and breathe out a soul aspiration towards a better land. Those who happen to be near a mosque, enter it for the purpose of performing their devotions; others are in their own houses; and many prostrate themselves by the wayside; or even on board the daily steamers. The mosques are always open, and there is an Imam who presides over the devotions.
