What is the benefit of feeding a fasting person and does this person have to be poor?

The Prophet (peace and blessings be upon him) said, “Whoever feeds a fasting person will have his sins forgiven, will be saved from hell fire, and will have the same reward as the fasting person without diminishing the reward of the fasting person in the slightest.” The Companions said, “Not all of us find that with which to feed a fasting person.” The Prophet replied, “God gives this reward to whoever breaks the fast of another even with a sip of milk, a date, or a drink of water.”

This hadith highlights the reward of feeding a fasting person and the rank this person has with God. In addition, this hadith shows that it is not a condition that the fasting person be poor as the wording is general and includes all those who fast. God is the Most Generous; even if the act of feeding a fasting person is minimal as is indicated in the hadith, the reward is achieved. God is Most High, All knowledgeable.
And God Almighty knows best.
