Scenario: A person affirms the Prophet Muhammad ﷺ but restricts his mission to one community and allows for a later prophet.
مَا كَانَ مُحَمَّدٌ أَبَا أَحَدٍ مِنْ رِجَالِكُمْ وَلَٰكِنْ رَسُولَ اللَّهِ وَخَاتَمَ النَّبِيِّينَ
Muhammad is not the father of any of your men, but is the Messenger of Allah and the Seal of the Prophets.
Governing principle: The mission of Muhammad ﷺ is universal and he is the final Prophet; these are distinct but connected teachings.
Sound application: Both the universality of his message and the finality of prophethood must be affirmed.
Limit of the conclusion: An extraordinary event associated with a saint cannot serve as evidence for new prophethood.
