Donation & Pleasing The Believers
The Holy Prophet (S) said: "When charity (alms) is delivered out of the hand of its owner, it (the thing being given) says five things: 'At first I was perishing and you gave me life; I was insignificant and you made me great; I was an enemy and you turned me into a friend; you used to protect me then but now I will protect you up to the Day of Resurrection'."
Al-Ithna 'Ashariyyah, p.223

Imam Amir-ul-Mu'mineen (‘a) said: Allah, the Glorified, has fixed the livelihood of the destitute in the wealth of the rich. Consequently, whenever a destitute remains hungry it is because some rich persons have denied him (his share)."
