The month of Adar containing Purim and the mitzva of giving gifts to the poor, stresses charity, as does the special Torah portion, called Shekalim, which is read this Shabbat.
Every individual must therefore add in charity. This applies in the physical sense, through the giving of money, food and drink. It also applies in the spiritual sense, through helping another person, giving advice, learning with him, etc.
(The Rebbe, 25 Shevat, 5751-1991)
