Who is the fasting person for whom the Muslim will be rewardedfor giving him food to break his fast with?

Is the fasting person who the Messenger (blessings and peace of Allah
be upon him) encouraged us to give him food to break his fast with the
poor person who is fasting, or one who is a stranger in the land, or
the one whom we invite to break the fast with us at home, such as a
guest who is part of the family or a relative? Can we attain the
reward by offering food for breaking the fast to fasting people to
whom we give a private invitation during Ramadan?.
Praise be to Allaah.
It is proven that the Prophet (blessings and peace of Allah be upon
him) said: "Whoever givesfood to a fasting person with which to break
his fast will have a reward like his without detractingfrom the reward
of the fasting person in the slightest."
Narrated by al-Tirmidhi, 807
What is meant by the fasting person here is any Muslim who is fasting,
especially those who are deserving of charity, such as the poor,
needy, and wayfarers. This is similar to the words of the Prophet
(blessings and peace of Allah be upon him): "Whoever equips a fighter
for the sake of Allah has gone out on campaign (i.e., will have the
reward of going out on campaign)."
Narrated by al-Bukhaari, 2843.
And Allah is the source of strength. May Allah send blessings and
peace upon our Prophet Muhammad and his family and Companions. End
