The Ima`m Reza(A.S.) spent all what he had on the poor and the miserable in Khurasan, so al-Fadl b. Sahl censured him for that, saying: "Surely this is (a kind of) damage!"
So the Imam answered him with a strong argument, saying: "Rather it is a profit; do not regard as damage that which results in reward and generosity.
It is not an act of damage when the Ima`m spent all what he had on the poor and the deprived in order to save them from poverty and misery; rather the damage was the enormous properties which the 'Abba`sid kings spent on their desires and their red nights, while they spent nothing on the poor from among the Muslims.
