Before the revelation of the Qur’an, the Jinn used to eavesdrop on snatches of information they heard in the lowest heavens between the angels. Suddenly they found that they could no longer intercept the messages, and found angels set as guards shooting meteorites at them if they went any way near. Distressed, they realised that it could only be as a result of a major event and searched the globe.
A group heard the Prophet (pbuh) and realised that it was the revelation of the Qur’an and went back to their community to report their findings and complain about how they were deceived by their ‘teacher’ Iblees (Shaytan). The chapter continues with their account about themselves and a response from Divinity asking the Prophet to declare to them that he is the Prophet.
