While the result of the embassy to Abyssinia was being looked for in Mecca with the greatest expectancy, there occurred the conversion of a man, who before had been one of the most bitter enemies of Muḥammad, and had opposed him with the utmost persistence and fanaticism—a man whom the Muslims had every reason then to look on as their most terrible and virulent enemy, though afterwards he shines as one of the noblest figures in the early history of Islam, viz. ʻUmar b. al-Khaṭṭāb. One day, in a fit of rage against the Prophet, he set out, sword in hand, to slay him. On the way, one of his relatives met him and asked him where he was going. “I am looking for Muḥammad,” he answered, “to kill the renegade who has brought discord among the Quraysh, called them fools, reviled their religion and defamed their gods.” “Why dost thou not rather punish those of thy own family, and set them right?” “And who are these of my own family?” answered ʻUmar. “Thy brother-in-law Saʻīd and thy sister Fāṭimah, who have become Muslims and followers of Muḥammad.” ʻUmar at once rushed off to the house of his sister, and found her with her husband and Khabbāb, another of the followers of Muḥammad, who was teaching them to recite a chapter of the Qurʼān. ʻUmar burst into the room: “What was that sound I heard?” “It was nothing,” they replied. “Nay, but I heard you, and I have learned that you have become followers of Muḥammad.” Whereupon he rushed upon Saʻīd and struck him. Fāṭimah threw herself between them, to protect her husband, crying, “Yes, we are Muslims; we believe in God and His Prophet: slay us if you will.” In the struggle his sister was wounded, and when ʻUmar saw the blood on her face, he was softened and asked to see the paper they had been reading: after some hesitation she handed it to him. It contained the 20th Sūrah of the Qurʼān. When ʻUmar read it, he exclaimed, “How beautiful, how sublime it is!” As he read on, conviction suddenly overpowered him and he cried, “Lead me to Muḥammad that I may tell him of my conversion.” [20] The conversion of ʻUmar is a turning-point in the history of Islam: the Muslims were now able to take up a bolder attitude. Muḥammad left the house of al-Arqam and the believers publicly performed their devotions together round the Kaʻbah. The situation might thus be expected to give the aristocracy of Mecca just cause for apprehension. For they had no longer to deal with a band of oppressed and despised outcasts, struggling for a weak and miserable existence. It was rather a powerful faction, adding daily to its strength by the accession of influential citizens and endangering the stability of the existing government by an alliance with a powerful foreign prince.
