It is narrated from Sayyiduna Wahshi bin Harb (may Allah be pleased with him) that the Companions of the Messenger of Allah (peace and blessings be upon him) said: O Messenger of Allah! We eat but we are not satisfied. He (peace and blessings be upon him) said: "Perhaps you eat separately?" They said: Yes. He (peace and blessings be upon him) said: "Then gather together for your food and mention the name of Allah over it; you will be blessed in it."
