Muwatta Malik, Book 32, Hadith 12 (USC-MSA) ⓘ

Yahya said that Malik said, "The generally agreed on way of doing things among us about an investor who pays qirad money to an agent to buy goods, and the agent then sells the goods for a price to be paid later, and has a profit in the transaction, then the agent dies before he has received payment, is that if his heirs want to take that money, they have their father's stipulated portion from the profit. That is theirs if they are trustworthy to take the payment. If they dislike to collect it from the debtor and they refer him to the investor, they are not obliged to collect it and there is nothing against them and nothing for them by their surrendering it to the investor. If they do collect it, they have a share of it and expenses like their father had. They are in the position of their father. If they are not trustworthy to do so, they can bring someone reliable and trustworthy to collect the money. If he collects all the capital and all the profit, they are in the position of their father." Malik spoke about an investor who paid qirad money to a man provided that he used it and was responsible for any delayed payment for which he sold it. He said, "This is obligatory on the agent. If he sells it for delayed payment, he is responsible for it."
