Some Muʿtazilī theologians objected that if a non-prophet could also experience extraordinary events, how would a prophet's miracle remain distinctive? The central concern is a supposed confusion between muʿjizah and karāmah.
The objection treats extraordinary character as a feature common to both and infers that the sign of prophecy would be undermined.
The reply depends on a fuller definition: a prophetic miracle is an extraordinary sign in the context of validating a specific prophetic claim.
