Foods (Kitab Al-At'imah)
Dawud :: Book 27 : Hadith 3755
Narrated Wahshi ibn Harb:
The Companions of the Prophet (peace_be_upon_him) said: Apostle of Allah (peace_be_upon_him) we eat but we are not satisfied. He said: Perhaps you eat separately. They replied: Yes. He said: If you gather together at your food and mention Allah's name, you will be blessed in it.
