One Muʿtazilī challenge asks: If God creates disbelief and wrongdoing, on what basis can the wrongdoer be punished or the obedient rewarded? The objection treats creating the act as equivalent to choosing and committing it.
The response distinguishes the two: humans receive commands and voluntarily obey or disobey; their acquisition is what is subject to moral and legal evaluation. God's origination of an act neither implies approval of the sin nor removes the servant's accountability.
It is also important not to collapse creative will into command and approval. These distinctions prevent the origination of an action from being confused with its moral evaluation.
