Some Muʿtazilī thinkers held that a servant can also be the agent or originator of certain effects that arise by generation (tawlīd) from a direct action. Their argument distinguished an effect proceeding through an intermediate act, such as pain after striking or fracture after impact.
This differs from attributing the creation of every such effect directly to Allah. It is not enough to say, “The person broke the glass.” One must decide whether the expression signifies ordinary attribution or existential origination.
Being called responsible for a consequence in ordinary speech does not by itself prove independent creative power.
