Zumar
Surah Az-Zumar is the 39th chapter of the Quran, named after the 'groups' or 'crowds' mentioned in verses discussing the Day of Judgment.
It refers to the distinct groups or companies of people who will be gathered on the Day of Resurrection—separated into believers and disbelievers.
Yes, though extremely rare, it is a valid Quranic name representing divine justice and community.
Because it refers to groups/crowds rather than a specific positive attribute or person, making parents hesitant, though it is textually authentic.
It is pronounced zu-MAR, with emphasis on the second syllable.
