Question:
hi, i signed up to give a monthly donation to a charity via credit card. ( i can cancel at any time ) can i now decide to use maaser money to pay the monthly donations.
Answer:
You can use the tzedakah towards maser money, because both are tzedakah. As a side point the preferred way to give maser is to keep a calculation of your earnings, and separate specifically a tenth, (and preferably a fifth) of our earning for maaser.
Best wishes
