The only official languages of the United Arab Emirates and Oman according to its consitution is Arabic. As you can see the primary name of all names in UAE and Oman is Arabic. 

According to the OSM guidelines the name tag must be in the native language.  Names in Russia are in Russian in Cyrillic alphabet, names in China are in Chinese in Chinese alphabet, names in Arab countries are in Arabic with Arabic alphabet. So please don't change the primary language without the local community consent, this is against OSM rules.
