I accidentally read the Megillah tonight for my shul since last year, I could have sworn, that we read the Megillah right after the fast. Yet, the Rav of the Shul returned from a business trip after the reading and told us that we erred since Purim cannot be celebrated on Fridays, it is נדחה (pushed off) until Sunday.
The question is: Should we repeat the Megillah tomorrow (Friday day) as well? I am compelled to read tomorrow, since the reason for reading during the day and night is because the Jews screamed out when they were in need by day and night (Rashi) - I do not want onlookers to think that they only screamed out during the night.
What do you think?
