A shiur led by Rabbi Nosson Lowenthal on 3/5/2023 discussing a parsha related to Purim.

If one forgets Al Hanisim in benching on Purim, does he need to repeat benching? This is connected if one has to wash and eat bread on Purim. The idea of washing on Purim would also be connected to the idea of having a Seuda the entire day. If one is supposed to have a Seuda the entire day on Purim, he would need to wash to make his Seuda one continuous meal.
