The virtues of Rasulullah became so clear that his integrity, loyalty and truthfulness gained great favour with the people of Makkah.
Hazrat Khadeejah-binte-Khuwaylid (R.A.) was a very rich business woman of Makkah and her trade extended to the realms of Syria (Shaam), Iraq and Yemen. She was so overwhelmed with Rasulullah's sublime character that she sent her nephew Qatima to him to find out if Rasulullah would accept a post as her trade agent. Rasulullah consulted his uncle Abu Taalib and accepted Hazrat Khadeejah (R.A.)'s proposition. She arranged a reasonable salary and Rasulullah set out on his second journey to Syria (Shaam), accompanied by Hazrat Khadeejah (R.A.)'s slave Maysarah and one of her relatives, Khazima-ibn-Hakeem.
When Rasulullah 's caravan camped at a site in Syria, Nasturaa, a monk, showed more than ordinary interest in Rasulullah and declared that according to their scriptures, Rasulullah was the expected 'Last of all Nabees'. The trade mission to Syria proved so profitable that Hazrat Khadeejah (R.A.) was overcome with admiration for Rasulullah . In due course, he made several other trips to Bahrain, Yemen and Syria each time returning with greater profit.
The exemplary character of Rasulullah was evident in many of his noble deeds. When his uncle Abu Taalib was hard pressed and in difficulty in a famine period, Rasulullah requested that he let him take custody of his children. Thus Rasulullah took care of Hazrat Ali-ibn-Abu Taalib while Hazrat Abbas (R.A.) cared for Hazrat Jafar-ibn-Abu Taalib.
Zaid-bin Haarith was a slave given to Rasulullah by Hazrat Khadeejah (R.A.). One day Zaid's father Haarith and his uncle Ka'ab came to Rasulullah to request the release of Zaid. Rasulullah readily granted Zaid his freedom. But Zaid refused to part from Rasulullah . Seeing this , Rasulullah promptly took Zaid with him to the court-yard of the Ka'bah and proclaimed Zaid as his own son before the people of Makkah.
