What is God's will concerning Iblis at the time he was commanded to prostrate to Adam (peace be upon him), based on the three possibilities mentioned in the atheistic message?

The confusion stems from not differentiating between the two types of Allah's will:

1. The Universal, Predestining Will (Al-Mashia): This must occur and includes what Allah loves (acts of obedience) and what He dislikes (sins). 2. The Legislative, Religious Will: This only pertains to what Allah loves and may or may not occur because people have free will.

Evil occurs by the Universal Will, not the Legislative Will. Thus, Iblis's refusal to prostrate was by Allah's Universal Will, whereas Allah willed him to prostrate by His Legislative Will and enabled him to do so, but he did not, and therefore he was punished. If Allah had willed his prostration universally, it would have occurred.
