- Question: Why can a drunk or blind man take challah from dough but cannot take Teruma from fruit?
A. One is not allowed to take teruma from bad quality fruit for good quality fruit.
B. One takes challah from a whole bowl of dough made from five pounds of flour.
Answer: There is no such thing as taking from the bad for the good by challah it is all the same dough so you can be drunk or blind when performing that mitzvah but by teruma you have to be cognizant enough to differentiate so they can’t do it. See Shach Yoreh Deah 328:2:4.
