And We have guarded it (near heaven) from every outcast Shaytan (devil). Except him (devil) who steals the hearing, then he is pursued by a clear flaming fire.
Allah made the "shooting stars" to guard it against the evil devils who try to listen to information conveyed at the highest heights. If any devil breaches it and advances hoping to listen, a clear "shooting star" comes to him and destroys him. He may already have passed on whatever he heard before the fire hit him, to another devil below him; the latter will then take it to his friends (among humans), as is stated in the Sahih. Explaining this Ayah, Al-Bukhari reported from Abu Hurayrah that the Prophet said;
إِذَا قَضَى اللهُ الاَْمْرَ فِي السَّمَاءِ ضَرَبَتِ الْمَلَيِكَةُ بِأَجْنِحَتِهَا خُضْعَانًا لِقَوْلِهِ كَأَنَّهُ سِلْسِلَةٌ عَلَى صَفْوَان
When Allah decrees any matter in heaven, the angels beat their wings in submission to His Word, (with a sound like) a chain (beating) on a smooth rock."
Ali and other sub narrators said, "The sound reaches them."
"When the fright leaves their (angels') hearts, they (angels) are asked;`What did your Lord say!'
They respond;"The truth. And He is the Most High, the Most Great.' So those who hope to hear something listen, and they are standing one above the other."
Sufyan (the narrator) described them with a gesture, spreading the fingers of his right hand and holding it in such a way that the fingers were above one another.
"Sometimes the flaming fire hits one of these listeners before he is able to convey what he has heard to the one who is beneath him, and he is burned up, or sometimes the fire does not hit him until he has pit on to the one beneath him, so he brings it to the earth."
Perhaps Sufyan said;"...until it reaches the earth and he puts it into the mouth of the sorcerer or fortune-teller, so that after telling a hundred lies he gets something right, and the people say, `Did he not tell us that on such and such a day such and such would happen, and we found it to be the truth among the statements which were heard from heaven."'
Then Allah says;
وَالَارْضَ مَدَدْنَاهَا وَأَلْقَيْنَا فِيهَا رَوَاسِيَ وَأَنبَتْنَا فِيهَا مِن كُلِّ شَيْءٍ مَّوْزُونٍ
