How Much Charity One Should Give?
Greed is addressed as a separate issue in Islam and it should not be intermixed with charity. If a person has surplus money and he’s called upon to help fulfill a genuine need of another person or the society then he is obligated to help with whatever he finds appropriate. Along with a portion of one’s wealth and earnings that is pre-determined by God’s law, one is strongly encouraged to help the best that he can in situations requiring his help. This creates the best possible balance; there can’t be any better way.
