Mitul Shah is Hindu. The majority of people with this surname are Hindu, but there are a great many Muslims, including famous ones, who also carry it.

Watched an Indian movie where an Indian Muslim man marries a Hindu woman in America. Their little business is destroyed after 9/11 because the bigoted Americans refuse to do business with a Muslim anymore.
How do they know they’re Muslim? The family surname is Khan. As if most Americans would know that Khan is a Muslim surname.
The Hindu version of the name is shortened from a longer Sanskrit word.
That said, Bollywood is disproportionately Muslim, and this is what my indian friends tell me.
