Removing Haman's name When Haman's name is recited out during the public reciting of the Megillah in the synagogue, which occurs 54 times, the congregation makes a lot of commotion to drown it out. This is because everyone knows how terrible and offensive he was that even the sound of his name should be removed from the text.
The Talmud (Megillah 14a) explains that since the death of Haman, no one has heard his name anymore except for the evil spirit that possessed him. Thus, when his name is read in the Megillah, the congregation makes so much noise so as not to hear it.
According to some opinions, the name Haman is not mentioned by its initial letters but rather by its final ones. Since these final letters are derived from a word meaning "enemy," they represent the end of someone who is evil toward G-d and His people. Therefore, when his name is said in the Megillah, we are actually saying "An enemy [at the end] of G-d."
Haman's role as an antagonist to the Jews warrants him having a prominent place in the Megillah. However, since he was also a prince of Persia, some opinions decline to include his name altogether, believing that this would diminish his importance.
The name Haman appears six times in the Qur'an, four times alongside Pharaoh and twice by himself, when God (Allah) sent Moses to call Pharaoh, Haman, and their people to monotheism and to seek protection for the Israelites who were being tormented by Haman and Pharaoh.
Haman was a king of the ancient Egyptians who refused to let the Israelites go. They wanted to kill all of them but Moses came along and saved the day by killing Haman. After his death, he was punished by being consumed alive by fire from the sky while he was still standing in his palace gate.
Pharaoh was another king who persecuted the Israelites but who later on will be among those who will surrender to Moses (peace be upon him).
Haman has become an important figure in Islam because Muslims believe that Jesus (peace be upon him) is also mentioned in the same chapter of the Qur'an as Haman. In fact, it says that "Moses said: 'Jesus, son of Mary, did you see me taken prisoner?' He said: 'Yes.' He said: 'Take courage; I have been given the news of your victory.'"
This verse proves that Jesus (peace be upon him) was alive at the time of his victory over Pharaoh and Haman because if he had already died then Moses would not have known anything about his victory.
In the Hebrew Bible, any of the five sacred volumes of the Ketuvim (the third section of the Old Testament), read in the synagogue at specified festivals. The first two Megillot are collections of poems; the third is a legal code. Although the term "megillah" is sometimes used generically to refer to any Jewish book, it usually refers to one of these three specific books.
Why do we read the megillah? Because it tells us what happened during this year's nine-month period of redemption. At the end of each year, all Jews have the duty to read the story of the past year, as recorded in the megillah, so that they may learn from its mistakes and succeed in avoiding its sins.
The megillah is read on certain holidays and days special to Israel. It is read on Rosh Hashanah, the New Year's Day festival, to remind Jews to review their lives and decide if they have done anything wrong and need to make amends before God. The megillah is read on Yom Kippur, the Day of Atonement, to ask for forgiveness for our sins and to seek God's help in order to change our ways.
