One of her uncles acted as her adviser in business matters, and other members of the family also assisted her in the management of business if and when she sought their assistance. But she didn't depend upon anyone else to make her decisions. She trusted her own judgment even though she welcomed advice and considered it. The senior members of her family knew that one thing she didn't like was paternalism.
Most of the traders who had cargo to sell in Syria or Yemen, travelled with the caravans to oversight all transactions in person. But there were occasions when a trader was unable to leave Makka. In such an event, he engaged a man to go in his stead, with the caravan. The man chosen for this purpose, had to be one with good reputation for his probity and for his sound business sense. Such a man was called an agent or a manager.
Khadija herself was a homebody and her brothers and cousins also did not show any interest in travelling with the caravans. She, therefore, recruited an agent whenever a caravan was outfitted to go abroad, and made him responsible for carrying her merchandize to the foreign markets and for selling it in those markets.
By judicious selection of her agents, and by selling and buying at the right time and at the right place, she was able to make fantastic profits, and in due course, became the richest merchant in Makka. Ibn Sa'ad says in his Tabaqat that whenever caravans of the Makkan merchants set out on their journey, the cargo of Khadija alone was equal to the cargo of all other merchants of Quraysh put together.
She had, it was obvious to everyone, the proverbial "golden touch." If she touched dust, it turned into gold. The citizens of Makka, therefore, bestowed upon her the title of the Princess of the Quraysh. They also called her the Princess of Makka. Arabia at this time was a pagan society, and the Arabs worshipped a multitude of idols and fetishes who, they believed, had the power to bring good fortune to them.
But their idolatry was crude and primitive, and their habits, customs and characteristics were repulsive. Drunkenness was one of their many vices, and they were incorrigible gamblers. They were wallowing in a pit of error and ignorance.
