What is a brief overview of the Nowruz holiday and its ruling in Islam, and how should one deal with a Baha'i neighbor?

Nowruz is the first day of the Coptic, Syriac, and Persian New Year, and its meaning is "New Day." The Copts have adopted it as a feast. It is not permissible for a Muslim to celebrate it or participate in it. As for the Baha'i neighbor, you must strive to guide him and seek help from books that refute Baha'ism. If he is not guided, then he only has the right of neighborliness, for the rights of neighbors differ: a close Muslim neighbor has three rights, a non-close Muslim neighbor has two rights, and a non-Muslim neighbor has only the right of neighborliness.
