Muhtadi
Yes. The form Al‑Muhtadi is attested historically as a regnal title (for example the Abbasid caliph Al‑Muhtadi, r. 869–870 CE), and the root/form has been used in Arabic epithets and later personal names.
Muhtadi (المهتدي) is derived from the root h‑d‑y (to guide) and means 'one who is rightly guided' or 'guided to the straight path.'
Muhtadi has been adopted in various Muslim communities, including Malay and Bosnian contexts, though it remains uncommon and is considered rare in modern naming practice.
Muhtadi is not one of the exclusive divine names requiring the 'Abd' construction; it is used independently as a given name in historical and modern contexts.
There is no widely attested feminine personal name exactly 'Muhtadi.' Feminine derivations in Arabic morphology could be formed (e.g., Muhtadiyya), but such forms are rare and not standard in historical records.
