Praise be to Allaah.
There is nothing wrong with this visitor eating from those
banquets, even if there is some extravagance in them as you say, but she
should advise the people of that household and explain to them the
importance of preserving blessings, giving thanks for them and not being
wasteful or extravagant in them. She should teach them to benefit from these
banquets by distributing surplus food to the poor and needy; thus they will
attain reward as well as celebrating their joy.
With regard to what some people do of wasting food and
throwing it away, this is wrong and is a transgression against the blessing
of Allaah, and it is helping the Shaytaan. Muslim (2033) narrated that
Jaabir said: I heard the Prophet (peace and blessings of Allaah be upon
him) say: “The shaytaan is present with any one of you in all his affairs,
and he is even present with him when he eats. If one of you drops a morsel,
let him remove any dirt that has gotten onto it, then eat it, and not leave
it for the shaytaan. And when he has finished let him lick his fingers, for
he does not know in which part of his food the blessing is.”
The Standing Committee was asked: What is your opinion about
leftover food, and food that is surplus to one’s needs? In the college they
offer different kinds of food, and the students eat a little and throw away
the rest.
They replied: Wasteful extravagance is forbidden, and wasting
money is forbidden. The leftover food should be kept for another time, or
given to the needy, and if there are no needy people then it should be given
to animals, even if that is after drying it out, for those who can manage
that.

May Allaah help us all to do that which He loves and which
pleases Him.
And Allaah knows best.
