Musannaf Ibn Abi Shayba 28:452

Waki’ narrated to us, he said: Hisham bin Sa’d narrated to us, from Zayd bin Aslam, from his father, who said: Spoils from the spoils of Jalula were brought to Umar bin al-Khattab, in which there was gold and silver. He began distributing them among the people. A son of his, who was called Abd al-Rahman, came and said: "O Commander of the Faithful, clothe me with a ring." He said: "Go to your mother so she may give you a drink of *sawiq* (barley meal drink)." He said: "And by Allah, he did not give him anything."
