Tzedakah or Ṣ'daqah in Classical Hebrew (Hebrew: צדקה‎; Arabic: صدقة‎) is a Hebrew word literally meaning righteousness but commonly used to signify charity. It is based on the Hebrew word (צדק, Tzedek) meaning righteousness, fairness or justice, and it is related to the Hebrew word Tzadik meaning righteous as an adjective (or righteous individual as a noun in the form of a substantive). In Judaism, tzedakah refers to the religious obligation to do what is right and just, which Judaism emphasises are important parts of living a spiritual life. Maimonides says that, while the second highest form of tzedakah is to anonymously give donations to unknown recipients, the highest form is to give a gift, loan, or partnership that will result in the recipient supporting himself instead of living upon others. Unlike philanthropy or charity, which are completely voluntary, tzedakah is seen as a religious obligation, which must be performed regardless of financial standing, and must even be performed by poor people. Tzedakah is considered to be one of the three main acts that can annul a less than favorable heavenly decree.
