The Gemoro (Megillah 14a)
says קרייתא זו הלילא. Reading the Megillah is the saying of Hallel. We don’t need to say Hallel on Purim, because reading the Megillah, is considered as the Hallel.
The מאירי
says, if someone didn't read (hear) the Megillah, he must say
Hallel on Purim. (to at least be Yotzei Mitzvas Hallel)
The
Gemoro (18b) says that R.Meir didn’t have a Megillah on Purim, so he wrote
one by heart.
The Chasam
Sofer (Shu”t O.Ch. 192) brings a Kushya from R. Yehuda Osad zt"l
"Why couldn’t R. Meir have said Hallel
instead of writing a whole Megillah?"
The
Chasam Sofer answered him a Tirutz.
My
Eidem asked, that "The Kushya doesn't even begin and
why the
need of the Chasam Sofer with a Tirutz?
The
Gemoro only says , by reading the Megillah you were
Yotze
Hallel , and not that by saying Hallel were you Yotze
Mikra
Megillah."
R. Meir
would not have been Yotzei Mikra Megillah by saying
Hallel and therefore had to write
a Megillah.
הפלא ופלא שהוא פלא עצומה שאין עליה תירוץ ודו״ק on the
