Upon his first settlement in Medina, which afterwards changed its original name of Jathripp into this new name, signifying the city, he built a mosque and arranged worship, in which a short prayer was offered five times a day. He sought at first to gain over the Jews residing there, and marked Jerusalem as the _Kiblah_, that is, the point to which the face should be turned in prayer, and the tenth day of the first month as a fast day, and allowed Jewish converts to keep the Sabbath.(87) But when he found that the Jews would receive a Messias only of the race of David he became their bitterest enemy. Later he appointed Mecca instead of Jerusalem as the Kiblah, the month Ramadhan as fasting time, and Friday as the day of rest. His first campaigns, when he could scarcely bring a few hundred men into the field, for the inhabitants of Medina had not yet joined him, but had only granted him protection, were but predatory attacks on the caravans of Mecca, which came near Medina. But when the Meccans grew prudent, and either defended their caravans with a strong escort, or sent them round by bye-paths to Syria, Mohammed planned a plundering attack in one of the holy months, when every Arab deemed himself secure. This is the beginning of a number of actions which, though he was not endued with a delicate moral sense, he must have known to be bad, and only ordered, or at least approved, for the sake of the end aimed at, chastisement of the heathen, and breaking in upon their commerce. What Mohammed did was to call his follower Abdallah, to give him a sealed packet, and instruct him to go to South Arabia with twelve companions. He was not to open the packet before the third day, and then fulfil the order it contained. Abdallah obeyed, broke the seal on the third day, and found only the words: Go with thy companions to the valley of Nachlah (south-east of Mecca), and there wait for the caravans of Mecca. Words which Abdallah interpreted to mean that he should fall upon these caravans. This he accomplished without difficulty. Two men were taken prisoners, one killed, and the whole lading carried as plunder to Medina. Mohammed had plainly used this short and sealed packet to cut off all explanation with Abdallah respecting an act of rapine in the sacred months, so as to be able to put away the responsibility from himself, as might be needed. Even the Moslim at Medina had but one cry of reprobation over this desecration of the sacred months. Mohammed at first disavowed Abdallah as having gone beyond his command, for he had not told him to attack the caravans in the sacred months. But when he found himself considered no less the author of this deed, and as he did not mean for the future to secure to Mecca four tranquil mouths for its commerce, Koran verses were published in which war against unbelievers was excused at every time, because they committed the much greater sin of driving the prophet out of his country.(88)
