Abdullah and Ubaydullah, the sons of Umar bin Khattab, went out with an army to Iraq. On their way back they passed by Abu Musa Ashari, who was the governor of Basra, and he welcomed them warmly and made them comfortable.Then he said, "If I could arrange something for you that would benefit you, I would do it."Then he added, "Actually, there is money here belonging to Allah which I intend to send to the Commander of the Believers. I will lend it to you, and you can buy goods from the merchandise of Iraq with it, then sell them in Madinah. You return the capital to the Commander of the Believers, and the profit will be yours."They said, "We would like that."So he did it, and he wrote to Umar bin Khattab telling him to take the money from them. When they arrived they sold the goods and made a profit. When they handed the money over to Umar, he asked, "Did he lend to every man in the army the way he lent to you?"They said, "No."Umar bin Khattab said, "You are the sons of the Commander of the Believers, so he lent to you. Hand over the money along with its profit."Abdullah said nothing, but Ubaydullah said, "This is not right of you, Commander of the Believers. If this money had decreased or been lost, we would have been liable for it."Umar said, "Hand it over."Abdullah remained silent, while Ubaydullah kept arguing with him. Then one of the men sitting with Umar said, "Commander of the Believers, why not treat it as a profit-sharing venture?"Umar said, "I have made it a profit-sharing venture."So Umar took the capital and half of the profit, and Abdullah and Ubaydullah, the sons of Umar bin Khattab, took the other half of the profit.
حدثني مالك
خرج عبد الله وعبيد الله ابنا عمر بن الخطاب في جيش إلى العراق فلما قفلا مرا على أبي موسى الأشعري وهو أمير البصرة فرحب بهما وسهل ثم قال لو أقدر لكما على أمر أنفعكما به لفعلت ثم قال بلى هاهنا مال من مال الله أريد أن أبعث به إلى أمير المؤمنين فأسلفكماه فتبتاعان به متاعا من متاع العراق ثم تبيعانه بالمدينة فتؤديان رأس المال إلى أمير المؤمنين ويكون الربح لكما فقالا وددنا ذلك ففعل وكتب إلى عمر بن الخطاب أن يأخذ منهما المال فلما قدما باعا فأربحا فلما دفعا ذلك إلى عمر قال أكل الجيش أسلفه مثل ما أسلفكما قالا لا فقال عمر بن الخطاب ابنا أمير المؤمنين فأسلفكما أديا المال وربحه فأما عبد الله فسكت وأما عبيد الله فقال ما ينبغي لك يا أمير المؤمنين هذا لو نقص هذا المال أو هلك لضمناه فقال عمر أدياه فسكت عبد الله وراجعه عبيد الله فقال رجل من جلساء عمر يا أمير المؤمنين لو جعلته قراضا فقال عمر قد جعلته قراضا فأخذ عمر رأس المال ونصف ربحه وأخذ عبد الله وعبيد الله ابنا عمر بن الخطاب نصف ربح المال
