Musannaf Ibn Abi Shaybah 37193 — The words of Umar bin al-Khattab

It is narrated from Rabi' bin Quzay' that he said: I heard Ibn Umar (may Allah be pleased with them both) say: Bread, meat, milk, olive oil, vegetables and vinegar used to be brought to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). He would eat, then lick his fingers. Then he would gesture like this, then rub one hand with the other and say: "These are the handkerchiefs of the family of Umar (may Allah be pleased with him)."
