Random question- what is the chiyuv of ad delo yada?
I always learned that there are 4 mitzvos of Purim- megilah, matanos la’evyonim, mishloach manos, and seudah.
Is the chiyuv ad delo yada part of the seudah in the sense that you have a big seudah, with bread and meat and wine, but you haven’t hit ad delo yada (according to whichever shitah) then you aren’t yotzei your seudah?
Or is ad delo yada a separate fifth chiyuv of Purim that can only be fulfilled during the seudah?
