Islamic scholars generally identify three categories of names that are impermissible. First, names that express servitude to anyone or anything other than Allah, such as Abd-un-Nabi (servant of the Prophet) or Abdul-Ka’aba (servant of the Ka’aba) — since worship and servitude belong to Allah alone. Second, names of idols, false deities, or figures associated with tyranny and disbelief mentioned negatively in the Quran, such as Firaun (Pharaoh) or names of pre-Islamic idols like Laat and Uzza. Third, names that claim an absolute or exclusive divine attribute for a human being, such as ‘Malik al-Amlak’ (King of Kings), which the Prophet (peace be upon him) specifically warned against as the most despised name before Allah (Sahih al-Bukhari and Muslim). All three categories are avoided because they conflict with Tawheed, the fundamental Islamic belief in Allah’s absolute oneness.
