A high-placed widow, Khadija, who had acquired in pre-Islamic days, by her virtue the titles of Tahira (the virtuous) and Saiyyadah-i Qoraish (the princess of the Qoraish), hearing of the righteousness of Muhammad, entrusted to him the sole charge of her business. He accepted an office in the service of Khadija and was immediately placed at the head of a caravan and sent to Syria accompanied by Maysara, one of the slaves of Khadija. Before long much profit accrued to her through his honest dealings. The personal attributes and moral grace in Muhammad attracted the attention and won the admiration of Khadija. So honestly Muhammad did transact the widow's trade that she caused a proposal of marriage, which met the approval of Abu Talib. Thus was he married, at the age of twenty-five, to a widow, fifteen years older than himself.
