LessonsThe Originator of the World: Necessary Existence, Infinite Regress and the Correspondence ProofQuiz

ولا يمكن أن يصدق مفهوم واجب الوجود إلا على ذات واحدة
The notion of the Necessary Existent can apply only to a single essence.

The text reserves intrinsic necessity and independence for the one ultimate ground of existents. Imagining two equally independent necessary beings prompts a further question: by what real feature would they differ, and would that differentiation entail composition or determination?

This question prepares for the fuller proof of divine unity; the present passage makes the concise claim. It must not be confused with the whole proof of mutual hindrance (*burhān al-tamānuʿ*), which begins in the next section.
