What is the ruling on previous doubt concerning an authentic prophetic miracle, and does that lead one out of Islam?

Belief in the miracles of the prophets is one of the fundamentals of faith, and it is obligatory for a Muslim to believe in their authenticity, as they are affirmed by texts and reality. And whoever believes in the miracles of the Prophet, peace and blessings be upon him, and affirms them, but denies an established miracle among them through interpretation, does not thereby become a disbeliever, but is considered an innovator.
