Narrated Wahshi ibn Harb: The Companions of the Prophet (ﷺ) said: Messenger of Allah (ﷺ) 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. Abu Dawud said: If you are invited to a wedding feast before you, do not take it until the owner of the house (i.e. the host) allows you (to eat)
