3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from abu ‘Umarah al-Tayyar who has said the following: “I once said to abu ‘Abd Allah , that my assets are gone, my belongings have scattered and I have a large family. Abu ‘Abd Allah , then said, ‘When you arrive in al-Kufah, open your shop, set up your display and balance and engage in (earning) sustenance from your Lord.’ Upon his arrival he opened his shop, set up his display and balance. People around found it strange knowing that there was nothing in his home of assets or with him. A man came to him and asked (and paid) him to buy for him cloths. He bought it (perhaps on credit) for him and received the payment for it which remained with him. Then another man came and said, ‘Buy for me a cloth.’ He searched in the market for him, and then bought it for him and the payment for it remained in his hand. This was how business people exchanged goods among themselves. Then another man came and said, ‘O abu ‘Ummarah, I have a bundle of Kattan. Do you want to buy it to pay me after one year?’ He replied, ‘Yes, load it and deliver to me.’ It was delivered to him and he bought it to pay after one year. The man then left and a man from the market came and asked, ‘O abu ‘Ummarah, what is this bundle?’ He replied, ‘I have purchased this bundle.’ He asked, ‘Can you sell to me one-half of it and keep the price with you?’ He then purchased it and he gave him one-half of the goods for a payment of one-half of the price which remained in his hand for one year. He then would buy cloths with that fund, put one or two cloths on display, buy and sell, until he became affluent, able to show his face and find fame.’”
