Praise be to Allah.
It is proven that the Prophet (blessings and peace of Allah be upon him) said: “Whoever gives food to a fasting person with which to break his fast will have a reward like his without detracting from 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 quote .
