Why did Allah stop the jinn from sneaking into the Heavens?

According to Islamic belief, Allah stopped the jinn from sneaking into the Heavens to protect the divine knowledge and secrets from being misused or corrupted. After the advent of Prophet Muhammad, the jinn were prevented from overhearing the heavenly conversations, as new revelations were being communicated to humanity. This was a sign of Allah’s protection over His message and a reminder of His power over all creation.
