After sharing the relevant verses from the Quran regarding the jinn, let us now examine the two hadiths narrated by the Rasul of Allah (saw): 

“At that time the jinn were unable to receive any information from the heavens. Whenever they attempted, flames of fire were sent onto them. Therefore, a distinguished one among them said: 

“Something must have happened recently, clearly a barrier has been put between us and the heavens! Let us navigate the earth to try and understand what has happened.” 

So, the jinn started to search all over the world for the source of the barrier. Those who went towards Tuhama came across the Rasul (saw) at a place called Nakhla, it was on the way to Suq 'Ukaz and the Rasul (saw) was offering the Fajr prayer with his companions. When they heard the Quran, they listened to it and said, "By Allah, this is the thing which has put a barrier between us and the news of heaven." They went back to their people and said, "O our people; verily we have heard a wonderful recital which shows the true path; we believed in it and would not ascribe partners to our Rabb."

It was after this that Allah revealed the chapter al-Jinn to his Rasul (saw).

The second hadith narrated by Ibn-i Masood (ra) is: 

The Rasul of Allah (saw) said, “I have been ordered to read the Quran to the jinn, so who will come with me?”

Everybody was silent. He asked for the second time. There was silence again. He asked for the third time and this time I replied: 

-Me, Abdullah! O, Rasul of Allah I will come with you. 

So, we stood up and walked together. 

When we came to the place called Hajoon near Doob Shib, he drew a line in front of me and said: 

-Do not go beyond this! 

Then, he went towards Hajoon.

They immediately flew over him like partridges. They resembled the ‘Zud’ group. They were playing their tambourines similar to the way the women played theirs. 

In the end, they surrounded him and he was lost from my sight. I stood up immediately from where I was sitting. At that moment, he made a gesture with his hand telling me to ‘sit down’. Then, he started to recite the Quran. His voice was becoming louder and louder as he continued reciting. They were all struck to the ground in a way that I was able to hear their voices, though I could not see them. 

Later, when the Rasul of Allah came near me, he asked: “You wanted to come with me, didn’t you?
I answered, “Yes, O Rasul of Allah!” He said, “It wasn’t necessary for you. They are the jinn! They came here to listen to the Quran, after which they went back to their community to warn them.” 

Now based on these hadith we can conclude the following:

1. Normally, the jinn were able to ascend to the higher levels (I will explain what I mean by this later) of the heavens and retrieve information regarding events that are to transpire in the future. 

2. After the revelation of the Quran or after the duty of Risalah was given to Muhammad (saw) the jinn were prevented from receiving information from the higher levels of the heavens. 

3. From this we may deduce that they could not perceive the entire world at the same time; for this they would need more time. 

4. The jinn are prevented from obtaining information from the higher levels of the heavens by objects known as Shihab (or meteors – objects that fall and burn when they come into contact with the atmosphere). 

5. They can make themselves denser and hence assume a material form.

6. Some among them can be given the duty of warning their community. 

7. They can make sound that is perceivable by the human ear.
