It is narrated from Hazrat Rabee’ bin Qazee’ that he says: I heard Ibn Umar (may Allah be pleased with them) say that bread, meat, milk, olives, vegetables, and vinegar used to be brought to Hazrat Umar bin Khattab (may Allah be pleased with him). He would eat the food and then lick his fingers. Then he would gesture in this manner. Then he would wipe one hand with the other and say: These are the napkins of the family of Umar (may Allah be pleased with him).
