Mobashir
No. Mobashir is not the name of a person in the Quran, but it is a legitimate Arabic lexical form (active participle) with a positive meaning used in Muslim naming.
In Urdu Mobashir is commonly rendered as خوشخبری سنانے والا or خوشخبری دینے والا, meaning 'one who brings good news.'
Bashir (بشير) means 'bringer of good news' in a concise form; Mobashir/Mubashir is the active participle variant with similar semantic field. All share the same b‑sh‑r root.
Yes. The form Mobashir/Mobasher appears in Persian and South Asian Muslim usage, though it remains less common than simpler names like Bashir.
Mobashir appears in modern and local historical records among Persianate and South Asian communities; it functions primarily as an ordinary given name rather than as a widely recorded historical epithet.
