Bhagvad Gita & Puranas:
Chapter 17,Verse 20:
दातव्यमिति यद्दानं दीयतेऽनुपकारिणे |
देशे काले च पात्रे च तद्दानं सात्त्विकं स्मृतम् || 20||
“Dharma has four basic tenets, one amongst which is the most important in the age of Kali—give in charity by whatever means possible.” The act of charity bestows many benefits. It reduces the attachment of the giver toward material objects; it develops the attitude of service; it expands the heart, and fosters the sentiment of compassion for others. Hence, most religious traditions follow the injunction of giving away one-tenth of one’s earnings in charity.
The Skandh Purāṇ states:
nyāyopārjita vittasya daśhamānśhena dhīmataḥ
kartavyo viniyogaśhcha īśhvaraprityarthameva cha [v7]
“From the wealth you have earned by rightful means, take out one-tenth, and as a matter of duty, give it away in charity. Dedicate your charity for the pleasure of God.” Charity is classified as proper or improper, superior or inferior, according to the factors mentioned by Shree Krishna in this verse. When it is offered freely from the heart to worthy recipients, at the proper time, and at the appropriate place, it is bequeathed to be in the mode of goodness.
What does Torah say about Giving/Charity?
Tzedakah is the Hebrew word for philanthropy and charity. It is a form of social justice in which donors benefit from giving as much or more than the recipients. So much more than a financial transaction, tzedakah builds trusting relationships and includes contributions of time, effort, and insight.
At the end of every Jewish worship service, the Aleinu prayer states a goal of the Jewish people to "perfect the world under the sovereignty of God." The term "perfect the world" in Hebrew is tikkun olam , which also means to fix or repair the world. The Torah claims "there will never cease to be needy ones in your land" (Deuteronomy 15:11)
