Allah says in Surah Insaan [76: 8-12]
“And they give food in spite of love for it to the needy, the orphan, and the captive,
[Saying], “We feed you only for the countenance of Allah. We wish not from you reward or gratitude.
Indeed, We fear from our Lord a Day austere and distressful.
So Allah will protect them from the evil of that Day and give them radiance and happiness.
And will reward them for what they patiently endured [with] a garden [in Paradise] and silk [garments].”
The Prophet (saw) said, ‘Whoever feeds a person breaking his fast will earn the same reward as him, without anything being lessened from the reward of the fasting person’. (Tirmidhi)
