Malik related to me from Zayd ibn Aslam that his father said, "Abdullah and Ubaydullah, the sons of Umar ibn al-Khattab went out with the army to Iraq. On the way home, they passed by Abu Musa al- Ashari who was the amir of Basra. He greeted them and made them welcome, and told them that if there was anything he could do to help them, he would do it. Then he said, 'There is some of the property of Allah which I want to send to the amir al-muminin, so I will lend it to you, and you can buy wares from Iraq and sell them in Madina. Then give the principal to the amir al-muminin, and you keep the profit.' They said that they would like to do it, and so he gave them the money and wrote to Umar ibn al-Khattab to take the money from them. When they came to sell they made a profit, and when they paid the principal to Umar he asked, 'Did he lend everyone in the army the like of what he lent you?' They said, 'No.' Umar ibn al-Khattab said, 'He made you the loan, because you are the sons of the amir al-muminin, so pay the principal and the profit.' Abdullah was silent. Ubaydullah said, 'You do not need to do this, amir al-muminin. Had the principal decreased or been destroyed, we would have guaranteed it.' Umar said, 'Pay it.' Abdullah was silent, and Ubaydullah repeated it. A man who was sitting with Umar said, 'Amir al-muminin, better that you make it a qirad. 'Umar said, 'I have made it qirad.' Umar then took the principal and half of the profit, and Abdullah and Ubaydullah, the sons of Umar ibn al-Khattab took half of the profit."

[Machine] "To send it to the Commander of the Faithful so that you both invest it in merchandise from Iraq, then sell it in the city, and deliver the capital to the Commander of the Faithful, and you both will make a profit." So they said, "We wish to do so." So he wrote to Umar to take money from both of them. When they arrived in the city, they sold and made a profit. When they reported this to Umar, he said, "Did the army lend them money as they lent you?" They said, "No." Umar said, "The sons of the Commander of the Faithful have lent you the money and its profit. As for Abdullah, he accepted it and as for Ubaidullah, he said, 'It is not appropriate for you, O Commander of the Faithful, if the money were to be lost or diminished, we would be responsible for it.' He ordered them to hand it over, so Abdullah remained silent, and Ubaidullah went back to Omar and a man from the companions of Umar bin Al-Khattab said, 'O Commander of the faithful, if you made it a loan.' He said, 'I have made it a loan.' So Umar took the money and half of its profit, and Abdullah and Ubaidullah took half of the profit. The meaning of their conversation is the same, except that Al-Shafi'i said in his narration, 'When they closed the transaction, they passed by a worker for Umar.'"
