Hadith 742

Wahshi bin Harb (May Allah be pleased with him) reported: Some of the Companions of Messenger of Allah (PBUH) said: "We eat but are not satisfied." He (PBUH) said, "Perhaps you eat separately." The Companions replied in affirmative. He then said: "Eat together and mention the Name of Allah over your food. It will be blessed for you."
