The institution is important, as indicating the development of Mahomet's religious and ritualistic conceptions. In the first days of his enthusiasm he was content to enjoin worship of one God by prayer and praise, taking secondary account of forms and ceremonies. Then came the uprooting of his outward religious life and the demands of his embryo state for the manifestations essential to a communistic faith. He found Israelite beliefs uncontaminated by the worship of many Gods, and turned to their ritual in the hope of establishing with their aid a ceremonial which should incorporate their system with his own fervent faith. Now, finding no middle road between separatism and absorption possible with such a people as the Jews, and unconsciously divining that in no great length of time Islam would be sufficient unto itself, he turned again to the practices of his native religion and ancestral ceremonies. Henceforth he puts forward definitely his conception of Islam as a purified and divinely regulated form of the worship followed by his Arabian forbears, purged of its idol-worship and freed from numerous age-long corruptions. Not only in ritual did his mind turn towards Mecca. It looms before his eyes still as the Chosen City, the city of his dreams, whose conquest and rendering back purified to the guidance of Allah he sets before his mind as the ultimate, dim-descried goal of all his intermediary wars. The Kibla had long since been changed to Mecca; thither at prayer every Muslim turned his face and directed his thoughts, and now every possible detail of ancient Meccan ritual was performed in scrupulous deference to the one God, so that when the time came and in fulfilment of his desires he set foot on its soil, no part of the ceremonies, with the lingering enthusiasm of his youth still sweet upon them, might be omitted or be allowed to lose its savour through disuse. The third year of the Hegira began favourably for Mahomet. During the first month, Muharram, there were three small expeditions against unruly desert tribes. The Beni Ghatafan on the eastern Babylonian route were friendly to the Kureisch. This was undesirable, because they might allow the Meccan caravan to pass through in safety, and the Prophet had resolved that it should be despoiled by whichever route it journeyed, coast road or arid tableland. When therefore he received news that they were assembling in force at Carcarat-al-Kadr, a desert oasis on the confines of their territory, he marched thither in haste, hoping to catch and overcome them before they dispersed. But the Beni Ghatafan were too wise to suffer this, and when Mahomet came to the place he found it deserted, save for some camels, left behind in the flight, which he captured and brought to Medina, deeming it useless to attempt the pursuit of his quarry through the trackless desert.
