On Feeding a Fasting Person
The Sahaba Radhiallaho anho said, "0 Messenger of Allah, not all of us possess the means whereby we can give a fasting person to break his fast." Rasulullah (SAW) replied, "Allah grants the same reward to the one who gives a fasting person to break the fast a mere date, or a drink of water, or a sip of milk."
"And whoever gave a person who fasted water to drink, Allah shall grant that giver to drink from My fountain, such a drink where after that person shall never again feel thirsty until he enters Jannah."
"Whosoever lessens the burden of his servants (bonds-men) in this month, Allah will forgive him and free him from the fire of Jahannam."[Hadith]
