"Charity that is given as a matter of duty, to a deserving candidate who does nothing in return, at the right place and time, is called a Saattvika or True charity."(Gita 17:20)
"But when you give a banquet, invite the poor, the crippled, the lame, the blind, and you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous." (Luke 14:13-14).
Holy Quoran exhorts Muslims to perform charity to attain the love of God and follow the path of righteous in the following words,
"You cannot attain to righteousness unless you spend (in charity) out of what you love." (The Holy Quran 3:92)
