“In the year 492 A. H.,” says Muir,[6] “consternation was spread throughout the land by the capture of Jerusalem, and cruel treatment of its inhabitants. Preachers went about proclaiming the sad story, kindling revenge, and rousing men to recover from infidel hands the Mosque of Omar, and scene of the Prophet’s heavenly flight. But whatever the success elsewhere, the mission failed in the East, which was occupied with its own troubles, and moreover cared little for the Holy Land, dominated as it then was by the Fatimide faith. Crowds of exiles, driven for refuge to Bagdad, and joined there by the populace, cried out for war against the Franks. But neither Sultan nor Caliph had ears to hear. For two Fridays the insurgents, with this cry, stormed the Great Mosque, broke the pulpit and throne of the Caliph in pieces, and shouted down the service; but that was all. No army went.” Among Moslems themselves religious rancour abounded. At present the four orthodox sects worship together and live in peace as neighbours, but in those days there were frequent and hot disputes between the rival schools and much controversial literature arose, so that the hatred between the sects was deep and bitter. The Persian historian, Mirkhond, has recorded a fact which shows how implacable the feeling had become towards the close of the Caliphate. When the Mongols of Genghiz Khan appeared before the city of Rei, they found it divided into two factions—the one composed of Shafiʾites, the other of Hanifites. The former at once entered into secret negotiations undertaking to deliver up the city at night, on condition that the Mongols massacred the members of the other sect. The Mongols, never reluctant to shed blood, gladly accepted these proposals, and being admitted into the city, slaughtered the Hanifites without mercy. It was in this atmosphere of mutual hatred, of war and bloodshed, that Al-Ghazali spent the last years of his life. We may excuse in him much of what would otherwise seem intolerant and hateful, when we remember how the passion of war blinds human judgment and makes it impossible to see any virtue in the invader.
