Faulty formulation: If an extraordinary event occurs through a saint, this establishes prophethood or permits a new revealed law.
Correct formulation: The possibility of saintly miracles (karāmāt) is affirmed, but a karāmah does not establish prophethood, legislative revelation or additions to the revealed law. The finality of prophethood remains intact.
Application: An extraordinary report calls for consideration of its reliability and conformity with revelation. Simply calling it a karāmah does not make a claim contrary to the Qur'an and Sunnah acceptable.
