Though warned by the Quraysh of the dangerous influence that Muḥammad might exercise over him if he entered into conversation with him, he followed the Prophet to his house one day, after watching him at prayer by the Kaʻbah. Muḥammad expounded to him the doctrines of Islam, and Ṭufayl left Mecca full of zeal for the new faith. On his return home he succeeded in converting his father and his wife, but found his fellow-tribesmen unwilling to abandon their old idolatrous worship. Disheartened at the ill-success of his mission, he returned to the Prophet and besought him to call down the curse of God on the Banū Daws; but Muḥammad encouraged him to persevere in his efforts, saying, “Return to thy people and summon them to the faith, but deal gently with them.” At the same time he prayed, “Oh God! guide the Banū Daws in the right way.” The success of Ṭufayl’s propaganda was such that in the year A.H. 7 he came to Medina with between seventy and eighty families of his tribesmen who had been won over to the faith of Islam, and after the triumphal entry of Muḥammad into Mecca, Ṭufayl set fire to the block of wood that had hitherto been venerated as the idol of the tribe. [35] In A.H. 7, fifteen more tribes submitted to the Prophet, and after the surrender of Mecca in A.H. 8, the ascendancy of Islam was assured, and those Arabs who had held aloof, saying, “Let Muḥammad and his fellow-tribesmen fight it out; if he is victorious, then is he a genuine prophet,” [36] now hastened to give in their allegiance to the new religion. Among those who came in after the fall of Mecca were some of the most bitter persecutors of Muḥammad in the earlier days of his mission, to whom his noble forbearance and forgiveness now gave a place in the brotherhood of Islam. The following year witnessed the martyrdom of ʻUrwah b. Masʻūd, one of the chiefs of the people of Ṭāʼif, which city the Muslims had unsuccessfully attempted to capture. He had been absent at that time in Yaman, and returned from his journey shortly after the raising of the siege. He had met the Prophet two years before at Ḥudaybiyyah, and had conceived a profound veneration for him, and now came to Medina to embrace the new faith. In the ardour of his zeal he offered to go to Ṭāʼif to convert his fellow-countrymen, and in spite of the efforts of Muḥammad to dissuade him from so dangerous an undertaking, he returned to his native city, publicly declared that he had renounced idolatry, and called upon the people to follow his example. While he was preaching, he was mortally wounded by an arrow, and died giving thanks to God for having granted him the glory of martyrdom. A more successful missionary effort was made by another follower of the Prophet in Yaman—probably a year later—of which we have the following graphic account: “The apostle of God wrote to al-Ḥārith and Masrūḥ, and Nuʻaym b. ʻAbd al-Kulāl of Ḥimyar: ‘Peace be upon you so long as ye believe on God and His apostle. God is one God, there is
