After the battle of Bozâkha, the Beni Asad, fearing lest their families should fall into the conqueror’s hand, tendered their submission. The Beni Aámir, Suleim, and Hawâzin, tribes which had stood aloof watching the event, now came in, and received from Khâlid the same terms as the Beni Asad. They resumed the profession of Islam with all its obligations, and in proof thereof brought in the tithe. A full amnesty was then accorded, on condition only that those who during the apostasy had taken the life of any Moslem should be delivered up. These were now (to carry out the Caliph’s vow) put to the like death as that which they had inflicted. If they had speared their victims, cast them over precipices, drowned them in wells, or burned them in the fire, the persecutors were now subjected to the same barbarous and cruel fate. [Sidenote: A body of malcontents under Omm Siml discomfited.] Khâlid stayed at Bozâkha for a month, receiving the submission of the people in the vicinity and their tithes. Troops of horse scoured the country, and struck terror into the vacillating tribes around. In only one direction was serious opposition met. Certain malcontents from amongst the penitent and returning people, unable to brook submission, gathered themselves together in a defiant attitude. They had yet to learn that the grip of Islam was stern and crushing. Their restless and marauding spirit preferred, perhaps, even as a forlorn hope, to hold their enemy at bay; or they had sinned beyond the hope of grace. Thus they assembled in a great multitude around Omm Siml, daughter of a famous chieftain of the Ghatafân. This lady’s mother, Omm Kirfa, had been captured and put to a cruel death by Mahomet. She herself had waited upon Ayesha as a captive maid in the Prophet’s household; but the haughty spirit of her race survived the servitude. Mounted on her mother’s war-camel, she led the force herself, and incited the insurgents to a bold resistance. Khâlid proclaimed the reward of one hundred camels to him who should maim her camel. It was soon disabled; and, Omm Siml slain, the rout was easy.[36] [Sidenote: Oyeina, Corra, and Alcama released by Abu Bekr.]
