Misbah
The noun misbah (مصباح, 'lamp') appears in the Quran’s Light Verse (An-Nur 24:35), making the root word Quranically attested; the use of Misbah as a personal name is a later onomastic adoption rather than a prophetic or Sahabi name.
Misbah is used as a unisex name in modern usage; cultural practice varies by region, but grammatically the word is neutral and families use it for either gender.
Misbah comes from the triliteral Arabic root ص-ب-ح (ṣ-b-ḥ) in contexts relating to light and morning; the noun مصباح is the active instrument noun meaning 'lamp'.
Misbah is attested in classical Arabic literature and religious texts as a common noun. Its adoption as a given name is documented in modern Muslim naming but it is relatively rare as a personal name.
Because of its meaning it commonly connotes illumination, guidance, clarity, and spiritual light — qualities valued in many Muslim naming contexts.
