RETURN OF OSÂMA. EXPEDITIONS FORMED AGAINST THE APOSTATE TRIBES THROUGHOUT ARABIA. A.H. XI. SEPT.--OCT. A.D. 632 [Sidenote: Osâma’s return. Jumâd II. A.H. XI. Sept. A.D. 632.] Osâma at last appeared, and Medîna, for two months left unprotected, was relieved from further danger. The army returned laden with booty. The royal Fifth was delivered to the Caliph, and by him distributed among the people.[20] [Sidenote: Expedition against Beni Abs and Dzobiân.] Abu Bekr lost no time in now following up the advantage he had gained over the Beni Abs and Dzobiân. Driven back from Dzul Cassa, they had retired to Rabadza, and vented their anger in destroying by cruel deaths the faithful followers of the Prophet still left amongst them. Deeply moved at the fate of these confessors, Abu Bekr took a solemn oath that ‘he would by the like deaths destroy as many of them as they had slain, or even more.’ [Sidenote: Abu Bekr chastises the rebel tribes at Rabadza.] Putting Osâma in command of the city, and leaving the army there for a little while to recruit, Abu Bekr took the remaining force and marched again towards Rabadza. The chief men expostulated with him on going forth to fight in person. If a commander were killed in action, his place could easily be filled; but if the Caliph fell, their head and ruler would be gone. ‘Nay,’ replied Abu Bekr; ‘but I will go forth, and will be your comrade even as one of your own selves.’[21] So they marched on, and coming up with the enemy at Abrac, completely discomfited them, killing some, and taking others prisoners. The Beni Abs and Dzobiân fled to Toleiha, and joined his army at Bozâkha. Thereupon Abu Bekr confiscated their pasture-lands, and declared them to be for ever a public domain reserved for the stud and camels of the State. On eventually submitting, they found themselves thus debarred from re-entry; but this was of comparatively little consequence, as they had, in the end, ample compensation in the conquered lands beyond Arabia. After some days spent at Rabadza, the Caliph returned to Medîna. [Sidenote: Islam must be reimposed on all Arabia.] The army by this time was refitted. The tithes had begun to come in from many neighbouring tribes in token of submission. Medîna was no longer in peril, and the citizens breathed freely. But a heavy burden still lay upon the Caliph. Islam was to be the faith of all Arabia;--‘Throughout the peninsula there shall be no second creed,’ was the behest of Mahomet on his death-bed. False prophets must be crushed; rebels vanquished; apostates reclaimed or exterminated; and the supremacy vindicated of Islam. It was, in short, the mission of Abu Bekr to redeem the dying Prophet’s words. [Sidenote: Eleven expeditions despatched to different parts of Arabia.]
