Musannaf Ibn Abi Shaybah

Hazrat Aslam narrates that the spoils of Jalula were brought to Hazrat Umar, and among them were gold and silver. He was distributing the spoils among the people when one of his sons, whose name was Abdur Rahman, came and said, "O Commander of the Faithful! Please give me a ring." Hazrat Umar said to him, "Go to your mother, she will give you a drink of barley water." He did not give him anything.
