Wahshi bin Harb bin Wahshi bin Harb narrated from his father, from his grandfather, that they said: “O Messenger of Allah, we eat and do not feel full.” He said: “Perhaps you eat separately?” They said: “Yes.” He said: “Gather to eat together, and mention the Name of Allah over it, then it will be blessed for you.”
