Hadith 5:473
Hafs narrated to us, from Muhammad ibn Zayd, from Umayr, the freed slave of Abu al-Lahm, who said: I was an owned slave, and I used to give charity. I asked the Prophet, may Allah bless him and grant him peace—and my master used to forbid me—or he asked him, and he said: "The reward is between you both."
حدثنا حفص عن محمد بن زيد عن عمير مولى أبي اللحم قال كنت عبدا مملوكا وكنت أتصدق فسألت النبي صلى الله عليه وسلم وكان مولاي ينهاني أو سأله فقال الأجر بينكما
