Answered by Shaykh Faraz Rabbani
Is there anything wrong in calling prominent saints and rulers “Maharaja” or king of kings? The title Maharaja was used by Muslims and Non-Muslims for rulers and saints for centuries.
I hope you’re doing well, insha’Allah.
While extravagant titles are in of themselves superior to avoid, they are not impermissible. This is because their affirmation to creation is considered to be in a (1) relative—not absolute and (2) hyperbolic—not literal—sense.
The term “Maharaja”—which means “great king,” according to the sources I’ve checked, is such a term. [“Maharaja” in Encyclopedia Britannica: https://www.britannica.com/topic/maharaja]
And Allah is the giver of success and facilitation.
