The second conquest of Arabia could scarcely have been achieved had not the Koreish stood by Abu-Bekr to a man. The leaders, who for years had striven against the prophet in the stricken field and lost their nearest kin in the struggle, had begun to realise (some of them before the taking of Mecca and the majority directly after) that they would gain enormously in power and consequence by the supremacy of a Koreishite. Mohammed’s marvellous success had made most of them to a certain extent believers. Several of those who had been his most zealous opponents afterwards fell or were severely wounded as champions of his religion. The commander who bore the brunt of the battle for the subjugation of the rebel Arabs, displaying an equal measure of sagacity and energy, was a Koreishite, Khalid ben al-Walid, the same who had been mainly responsible for the victory of the Koreish over the hosts of Mohammed at Mount Ohod, close by Medina, eight years before. MOSLEM CONQUESTS Arabia was hardly reconquered before the great invasion of other countries began. The prophet himself had set on foot some enterprises against Syria, but without any particular result. The great thing now to be accomplished was to transform the Arab hordes from recalcitrant subjects into joyful warriors of God by the twofold prospect of earthly spoil and heavenly rewards. Here we recognise the hand of Omar, to whom the sovereignty passed directly on the death of Abu-Bekr soon after. The wars of conquest which he inaugurated were crowned with brilliant success. It is worth while to consider the subject briefly in detail.
