Mubashir
Yes. Mubashir is Arabic in origin, derived from the root b-š-r meaning to give tidings; it has classical Arabic usage and is used in Urdu-speaking communities as well.
In Urdu Mubashir is understood as 'خوشخبری دینے والا' which literally means 'one who brings good news'.
No specific person named Mubashir appears in the Qur'an as a proper name; however, the root b-š-r (relating to glad tidings) occurs in Qur'anic vocabulary.
Mubashir is uncommon to rare in many regions; it is more often encountered in literary or religious contexts rather than as a highly popular modern given name.
Related names include Bashir and Basheer (sharing the same root b-š-r), and alternative spellings such as Mubasher.
