I heard that if you read Megillah as a historical document you are not yeotzei, but rather you must contemporaneous. Is this true? What is the source of this Halacha?
Thank you and Purim Samayach.
Answer:
No, I have never heard of this halachah.
Also, I don’t understand it. The Megillah tells a tale of what happened. It is of course a historical document (though of course one of the Kisvei Ha-Kodesh), yet at the same time it is an instructional document — a part of Torah — that carries eternal lessons about the eternity of Klal Yisrael.
Best wishes.
