For about a month affairs took their normal and uninterrupted course in Medina, but in the following month, Dzul Higg (March), the last of that eventful second year, a slight disturbance of his steady work of government threatened his followers. Abu Sofian's vow pressed sorely upon his conscience until, unable to endure inaction further, he gathered together 200 horsemen and took the highway towards Medina. He travelled by the inland road, and arrived at length at the settlements of the Beni Nadhir, one of the Jewish tribes in the vicinity of Medina. He harried their palm-gardens, burnt their cornfields, and killed two of their men. Mahomet had plundered the Meccan wealth, his allies should in turn be harassed by his victims. It was purely a private enterprise undertaken out of bravado and in fulfilment of a vow. As soon as the predatory attack had been made, Abu Sofian deemed himself absolved and prepared to return. But Mahomet was on his traces. For five days he pursued the flying Kureisch, whose retreat turned into such a headlong rout that they threw away their sacks of meal so as to travel more lightly. Therefore the incident has been known ever since, according to the vivid Arab method of description, as the Battle of the Meal-bags. But the foe was not worthy of his pursuit, and Mahomet made no further attempt to come up with Abu Sofian, but returned at once to Medina. The attack had ended more or less in fiasco, and as a trial of strength upon either side it was negligible. The sacred month, Dzul Higg, and the only one in which it was lawful to make the Greater Pilgrimage in far-off Mecca, was now fully upon him, and Mahomet felt drawn irresistibly to the ceremonies surrounding the ancient and now to him distorted faith. He felt compelled to acknowledge his kinship with the ancient ritual of Arabia, and to this end appointed a festival, Eed-al-Zoha, to be celebrated in this month, which was not only to take the place of the Jewish sacrificial ceremony, but to strengthen his connection with the rites still performed at Mecca, of which the Kaaba and the Black Stone formed the emblem and the goal. In commemoration of the ceremonial slaying of victims in the vale of Mina at the end of the Greater Pilgrimage, Mahomet ordered two kids to be sacrificed at every festival, so that his people were continually reminded that at Mecca, beneath the infidel yoke, the sacred ritual, so peculiarly their own by virtue of the Abrahamic descent and their inexorable monotheism, was being unworthily performed.
