Mohammed, from the very character of his religion, could not let the sword rust in its sheath so long as Islam had not attained supremacy. Consequently he continued to lead his followers on warlike expeditions against both Jew and heathen. The fact that he himself took part in all the fights was a great spur to the spirit and courage of his troops; more than once his life was in danger, but a higher power protected God’s envoy; the sword fell from a hostile leader who waved it above his head. Since the battle of Ohod most of the attacks had been directed against the Jews, who showed themselves more and more hostile to the new religion. They found a protector in Abdallah ben Obayyah, the chief of the Khazraj, who, jealous of Mohammed’s growing power amongst his followers, toiled against the prophet. The Beni Nadir were driven from their strong castles, after their date palms had been cut down, in defiance of the usages of Arabian warfare; and they owed their lives solely to the powerful intercession of Abdallah, but were nevertheless compelled to quit the Arabian country like the Beni Kainoka before them. But the “hypocrites” continued to work against Mohammed’s power after a victorious campaign against the powerful tribe of the Beni Mustalik; Abdallah excited a quarrel between the “helpers” and the immigrant believers, which was only adjusted by the skill and prompt decision of the prophet. A saying of the Koran gave warning against hypocrites, but this time also Abdallah escaped punishment. Even the evil reports concerning Aisha’s virtue and marital fidelity, which he and others put into circulation about that time because she was left behind on a night march and entered the camp on the second day in the company of a man, were overlooked. Mohammed, in accordance with a revelation, declared the rumours to be slanders, punished the calumniators who, like the poet Hassan, maintained her guilt, and cherished Aisha with fresh tenderness; but Abdallah remained unpunished. Mohammed dreaded the revenge of the Khazraj. SIEGE OF MEDINA, EXTERMINATION OF THE JEWS (627-628 A.D.) [Sidenote: [627-628 A.D.]]
