Hazrat Muhammad Mustafa saww said:
“Whoever provides iftar for a fasting person in it (Ramadan), then that shall be forgiven for his (the feeder’s) [minor] sis and freedom from fire.
And for such a feeder shall be the same reward as the one who fasted (whom he fed) without that person’s reward being decreased in the last”.
[Ibn Khuzaimah]
The Messenger of Allah (saww) also said:
‘(O people!) Save yourselves from the Fire even if it is with half a date, and if you cannot find that, then (save yourselves by saying) a good word’. [Muslim]
