With sudden contrast, we turn our attention to the most important problem in the daily life of the Arab— religion. Now, it is a curious thing that in practically all European countries religion has not much sway over the general masses, and that frequently it is subject-matter for controversy and discord. Even among those members of the community who are still faithful believers, the church is not really interwoven in the hum of daily life. Not so in Algeria. Every Arab who has not been degenerated by Europe into atheism— and it must be admitted that there are very few of these—believes in Allah, believes in Mohammed, in the world to come, with eternal damnation or salvation. But not only does he believe it to the extent of practising the religion in the mosque as European believers do in the church, but he continues following the precepts of the Faith in every moment of his life. After living a while with the Arabs it comes as a revelation quite unexpected, and it makes one wonder whether Mohammed, thirteen hundred years ago, had any idea what effect his preaching would have on his followers; probably not. He always strikes one as a man who was almost forced into the path which he followed by circumstances about him. However, these pages are not the place to raise this question. What is certain is the immense change which swept over North Africa when the Arab invasions began in the seventh century, bringing with them all the doctrines of the new faith into a land full of rival beliefs. There is less difference in Algeria between that period and the present than there was between the sixth century and the days of Carthage in all its splendor, and whether we are discussing the Arabs of the north or of the Sahara, or whether the Berbers of the Kabyle Mountains or those of the Mzab, there is one expression which covers them all: “They are Mohammedans.” Not all Mohammedans are of the same denomination, but they are much less divided than the different sects in England, and all with the same fervent belief: _La ilahah ill Allah, Mohammed Rasoul Allah._ There is no God but God, and Mohammed is his prophet. Mohammedanism is, moreover, in itself a complete solution to all the problems of life, both temporal and spiritual. It is not only a teaching of religious principles, but also the framework of all social laws, and a person who follows its precepts will have not only a clean soul, but also a clean body. The ablutions, the forbidden meats and wines, the many postures taken during the prayer five times a day, were all invented with a purpose. The Arab was dirty by nature; he was told to wash before saying his prayers; in cases where water lacked, to clean himself with sand. It was known that pork was bad for people living in hot countries; it was forbidden. The laziness of the Oriental is proverbial; physical exercises were devised for him in his daily prayers before Mr. Sandow and his disciples thought of the present-day training.
