Reference for Pesachim 65:4

ומתקיף לה רב פפא ממאי דרבי כרבנן סבירא ליה דילמא כאבא שאול סבירא ליה דאמר יש בה שוה פרוטה אע"ג דלית בה כזית

perhaps he agrees with Abba Saul, who said: If it possesses the worth of a perutah, even if it does not contain as much as an olive?<span class="x" onmousemove="('comment',' Hence the same applies to trespass too, and thus R. Hiyya b. Abin's answer is correct.');">⁷</span> But surely it was R'Papa who said [that] Abba Saul requires both? Hence this proves that he retracted.
