What is the ruling on screaming in the mosque at someone who insists on naming the mosque "Ahl al-Hadith" and refuses to be content with naming it "Masjid al-Rahman"?

Naming a mosque after one of Allah’s Beautiful Names, such as "Masjid Al-Rahman," is an innovation that is better avoided, because all mosques belong to Allah without any specific dedication. As for naming a mosque "Masjid Ahl al-Hadith," this is permissible because it is a religiously acceptable description. However, one must consider the reality of the country; if this naming leads to disunity among Muslims or incites discord and partisanship, then it must be avoided. If the mosque's congregation insists on this name, there is no harm in it, especially if changing the name would cause the congregation to become alienated or confused. In summary, reconciliation among the mosque's congregation and mending relations is preferable to adhering to names that might provoke disagreement.
