Sheikh Kulaini in his book Al Kaafi relates the following tradition from Imam Jaffer Sadiq (a.s.): "Cure your sick by giving sadaqa or charity, and remove troubles and mishaps by giving charity, and increase sustenance with charity. Charity banishes seventy shaitans from what is within one's beard, and charity goes unto the hand of Allah (s.w.t) before it goes unto the hand of the needy". (BIHAR VOL 96 PAGE 129)

Our Holy Prophet (s.a.w.w.) says that: "We should give charity as it increases our property, and it makes the mercy of Allah befall on us". (BIHAR VOL 96)

Once Abu Abdillah (a.s.) asked his son how much money he had. His son replied that he only had forty dinaars. Abu Abdillah (a.s.) asked his son to give it all away in the way of Allah. His son was hesitant and said that it was the only meager amount he possessed.

His father replied that: "Charity was the key to sustenance".

Shortly after having given the amount in charity the Imam's son got four thousand dirhams. The Imam (a.s.) said to his son: "O son, we gave Allah forty dirhams and he gave us four thousand." (BIHAR VOL 47 PAGE 38)
