And so it came to pass. They tarried but three days, when a surprise was attempted from Dzul Cassa. The outposts were on the alert, and kept the assailants at bay while the main guard was hurried up from the Mosque on camels. The Bedouins, hardly prepared for so warm a reception, fled back upon their reserves. They were pursued; but the camels of the Moslems, being used only to draw water for the fields, took fright at a stratagem of the enemy, and turning, fled back to the Mosque.[18] There were no casualties among the Medîna troops, but the rebels were emboldened by the flight of their opponents. Abu Bekr, anticipating a renewed attack, called out every man capable of bearing arms, and spent the night in marshalling his force. Next morning, while yet dark, the Caliph himself led out the little band in regular array, with a centre and two wings.[19] The enemy were taken by surprise at early dawn, and as the sun rose were already in full flight. Abu Bekr drove them with slaughter out of Dzul Cassa, and, leaving a portion of his little force as an outpost there, returned with the rest to Medîna. [Sidenote: Good effect of the victory.] The affair was comparatively small, but its effect great. As failure would have been disastrous, perhaps fatal, to Islam, so victory was the turning-point in its favour. The power of the Prophet’s successor, even without his proper army, to secure the city and beat off his assailants was noised abroad. And soon after, the spirits of the Moslems rose as they saw certain chiefs appear, bringing in the tithes. The tribes they represented, to be sure, were few in contrast with the apostate hordes; but it was an augury of brighter days to come. Safwân and Zibricân, chiefs of two branches of the Beni Temîm, and Adi son of Hâtim from a loyal branch of the Beni Tay, were the first to present their legal offerings to the Caliph. Each was ushered into his presence as an ambassador. ‘Nay,’ said Abu Bekr; ‘they are more than that; they are Messengers of glad tidings, true men, and defenders of the faith.’ And the people answered, ‘Even so; now the good things that thou didst promise are appearing.’ [Sidenote: Saving of Islam due to Abu Bekr.] Tradition delights to ascribe with pious gratitude the preservation of Islam to the aged Caliph’s faith and fortitude. ‘On the death of Mahomet,’ we are told, ‘it wanted but little, and the faithful had utterly perished. But the Lord strengthened the heart of Abu Bekr, and stablished us thereby in the resolve to give place, no not for one moment, to the apostates; and to say but these three words--_Submission_, _Exile_, or the _Sword_.’ It was the simple faith in Mahomet of Abu Bekr which fitted him for the task, and made him carry out the law of his Master to the very letter. But for him, Islam would have melted away in compromise with the Bedouin tribes, or might have perished in the throes of its birth. CHAPTER IV.
