Question
Is it valid to use surplus from usurious money for the sacrifice, knowing that this money was not initially taken for the purpose of the sacrifice, but rather taken for building a house?
Answer
I say, and with God's success: The sacrifice is valid from a loan obtained through usury; because it is not impure money, but rather the act resulting from it is forbidden, and it is a great sin. And God knows best.
And God knows best.
