Qutayba bin Sa'id bin Jamil قتيبة بن سعيد بن جميل · Foods (Kitab Al-At'imah)

The worst kind of food is that at a wedding feast to which the rich are invited and from which the poor are left out. If anyone does not attend the feast to which he was invited, he has disobeyed Allah and His Apostle (may peace upon him).

The Prophet (ﷺ) said: If any Muslim is a guest of people and is given nothing, it is the duty of every Muslim to help him to the extent of taking for him from their crop and property for the entertainment of one night.
