הלכה אויף ישעיהו 65:16

All Prophetic Books and the Sacred Writings will cease [to be recited in public] during the messianic era except the Book of Esther. It will continue to exist just as the Five Books of the Torah and the laws of the Oral Torah that will never cease. Although ancient troubles will be remembered no longer, as it is written: "The troubles of the past are forgotten and hidden from my eyes" (Isaiah 65:16), the days of Purim will not be abolished, as it is written: "These days of Purim shall never be repealed among the Jews, and the memory of them shall never cease from their descendants" (Esther 9:28).
