Musannaf Ibn Abi Shaybah

Hazrat Aswad bin Mukhramah narrates that Hazrat Sa’d bought a basin from a man of Hira for one thousand dirhams. He was informed that Hazrat Umar had come to know of this and was very displeased with him. After that, Hazrat Sa’d kept searching for that Christian, and after finding him, returned the basin to him and took back the one thousand dirhams.
