أعوذ بالله من الشيطان الرجيم
وَيُطْعِمُونَ الطَّعَامَ عَلَىٰ حُبِّهِ مِسْكِينًا وَيَتِيمًا وَأَسِيرًا ﴿٨﴾ إِنَّمَا نُطْعِمُكُمْ لِوَجْهِ اللَّـهِ لَا نُرِيدُ مِنكُمْ جَزَاءً وَلَا شُكُورًا

And they feed, for the love of Allah, the indigent, the orphan, and the captive,-
(Saying),”We feed you for the sake of Allah alone: no reward do we desire from you, nor thanks.

—Quran, sura 76 (Al-Insan), ayat 8-9

Abu Musa Al-Ash`ari (may Allah be pleased with him) reported: The Prophet (sal Allahu alayhi wa sallam) said, “Giving in charity is an obligation upon every Muslim. It was said (to him): “What about one who does not find (the means) to do so?” He said, “Let him work with his hands, thus doing benefit to himself, and give in charity.” It was said to him: “What if he does not have (the means) to do so?” He said, “Then let him assist the needy, the aggrieved.” It was said: “What about if he cannot even do this?” He said, “Then he should enjoin good.” He was asked: “What if he cannot do that?” He said, “He should then abstain from evil, for verily, that is a charity from him.” [Bukhari and Muslim]
