What should I do regarding a neighbor who defaced the names of the Rightly Guided Caliphs and replaced "may Allah be pleased with him" with "may Allah curse him" in my daughter's book, considering the Prophet's (peace and blessings be upon him) injunctions regarding neighbors?

The rights of a neighbor entail loving good for them and striving for their guidance, and preventing them from committing sins. The Prophet, peace and blessings be upon him, warned against cursing someone who does not deserve to be cursed, explaining that the curse returns to the one who utters it if it does not find someone deserving, and that cursing a brother is considered a major sin. The Rightly Guided Caliphs do not deserve to be cursed, and the curse returns to anyone who curses them. The Prophet, peace and blessings be upon him, clarified the virtue and status of the Companions, and urged to preserve their rights, honor them, and not harm them, emphasizing that they are the best of people, and he forbade reviling them. He also stressed the obligation to follow the Sunnah of the Rightly Guided Caliphs. Therefore, you should advise your neighbor by explaining the seriousness of cursing the Companions and the obligation to love them, and to raise her children upon that, and to defend the Caliphs. If she insists on hating them, then be wary of her and warn your children against being influenced by her children, while continuing to strive for her guidance through supplication and various da'wah means, because whoever defends the honor of his Muslim brother, Allah will avert the Fire from him on the Day of Resurrection, so what about the Companions and the Rightly Guided Caliphs?
