A few quotes from the Rabbi on 'Tzedakah and Healing'
in which he teaches to give twice to the poor person, once to appease his suffering and once to fulfill the commandment.
"Rav said to Rav Hamnuna: My son, if you have [money], do well for yourself. [There is no point waiting,] as there is no pleasure in the netherworld, and death does not tarry. Should you say: I will leave for my children, who told you the law of the netherworld [which of you will die first]?" If you have been privileged with wealth, distribute it yourself as early in life as you can to benefit your soul, do not tarry. The reason given is that should your inclination seek to seduce you into giving to charity after you reach the netherworld, the Almighty will not be pleased. The Almighty's principal appreciation comes from a person's deeds while he is living and owns his choices, by a person who is held back by his inclination, yet overcomes his inclination. Should you say that you are still a young man and that you have the time to distribute [charity] during your life after you age, the text for this reason it says, "and death does not tarry" – lest you die early in your youth. Should you say, "I will leave for my children" – I do not wish to distribute charity at all, not during my life nor after my death and will only leave all the wealth as an inheritance to my children – this, too, is absurd and foolish.
