But more effectual help to quell the disordered country was soon at hand. On one side, Mohâjir was marching from the north. Appointed by the Prophet his lieutenant in Hadhramaut, he had long been detained by sickness at Medîna, and perhaps also by the inability of the Caliph to furnish him with a following. He was the last of the commanders sent forth by Abu Bekr to reclaim the backsliding tribes. Passing through Tâyif and Najrân, as late, probably, as ten or twelve months after the death of Mahomet,[83] he was joined on the way by various loyal tribes, and thus approached the disturbed country at the head of a substantial force. On the other side, Ikrima, with his great and ever-growing army, was advancing from the east. Hastening to meet Mohâjir, he, for the present, left Hadhramaut on his right, and passed rapidly on to Aden. Alarmed at the gathering storm, Cays ibn Abd Yaghûth and Amr ibn Mádekerib had joined their forces to oppose Mohâjir. But soon quarrelling, they parted, and, according to the wont of Arab poets, abused each other in insulting verse.[84] Amr, perceiving opposition to be now in vain, sought, by a strange expedient, to gain his safety. He made a night attack upon Cays, and carried him prisoner to Mohâjir; but he had forgotten a safe-conduct for himself. Mohâjir, therefore, seized them both, and sent them in chains to Medîna. The Caliph was at first minded to put Amr to death because of the murder of Dâdweih; but he denied the crime, and there was no evidence to prove it. ‘Art thou not ashamed,’ said Abu Bekr to him, ‘that following the rebel cause, thou art ever either a fugitive or in bonds? Hadst thou been a defender of the Faith instead, then had the Lord raised thee above thy fellows.’ ‘So assuredly it is,’ replied the humbled chief; ‘I will embrace the faith, and never again will I desert it.’ So the Caliph forgave them both; and his clemency was not abused, for we find these gallant but unscrupulous chiefs soon after fighting loyally in the Persian war. [Sidenote: Peace restored in Yemen.] After this, Yemen was speedily reduced to order. The rebel horse, remnant of the false prophet’s army, was pursued without quarter, and soon exterminated. And Mohâjir, established firmly at Sanâa, ruled in security over the whole of that country, from Najrân to Aden. [Sidenote: Rebellion in Hadhramaut under Ashâth ibn Cays.]
