Sayyiduna Wahshi (may Allah be pleased with him) narrates: The people said, "O Messenger of Allah! We eat but do not feel satiated." The Prophet (peace and blessings be upon him) asked, "Do you eat together or separately?" They replied, "We eat separately." The Prophet (peace and blessings be upon him) said, "Eat together and mention the name of Allah over it. There will be blessing in it for you."
