What is the ruling on insulting Arabs?

It is not permissible to curse Arabs generally, because the Prophet, peace and blessings be upon him, and the greatest of his companions were among them, and cursing them is worse than cursing others. It has been narrated from the Prophet, peace and blessings be upon him, his saying: "Indeed, Allah created creation, and He chose from creation the children of Adam, and He chose from the children of Adam the Arabs, and He chose from the Arabs Mudar, and He chose from Mudar Quraysh, and He chose from Quraysh Banu Hashim. So I am from the best to the best. Whoever loves the Arabs, it is out of love for me that he loves them, and whoever hates the Arabs, it is out of hatred for me that he hates them." And whoever curses them because the Prophet, peace and blessings be upon him, was among them, this is hypocrisy and heresy. One should be wary of the weak hadith: "Whoever curses the Arabs, those are the polytheists in Allah."
