Several historical debates are reported between Muʿtazilī and Sunni scholars. They revolve around questions such as “If God willed this, why did it not happen?” and “Does issuing a command entail willing its fulfillment as an event?”.
The examples are meant to distinguish the existence of a command, a human's disobedience, and the meaning assigned to divine volition. A brief anecdote is not itself a complete demonstrative proof of the doctrine; its relevance is the conceptual distinction it highlights.
An example using the phrase “the predominant partner” is reported as a polemical illustration. It does not establish any acceptable partnership with God; it exposes the implications of the rival description of will and occurrence.
