The entire narrative framework of Surah 72 relies on an event that is completely unfalsifiable, breaking the standard of reliable historical testimony.
Surah 72:1:
Say, 'It has been revealed to me that a group of the jinn listened and said, "Indeed, we have heard an amazing Qur'an."
Muhammad did not actually see or hear the Jinn himself. The verse explicitly states that it was "revealed" to him that they were listening.
This creates a closed, unverifiable loop. Muhammad uses a revelation from his private source to claim that invisible creatures were listening to him, and then uses their alleged praise as proof that his message is divine.
Unlike Biblical miracles and prophecies that occurred in the open before thousands of eyewitnesses, this chapter relies entirely on an invisible, spectral endorsement that no human could ever verify. It is worthless.
