Peace,
From the following verses, I understand Aljinn et aljinns. As two different creations.
Like human beings, Aljinn have feet, hearts, eyes, ears, offspring, soldiers, nations, they speak, warn, think, create and have received messengers among them.
72:1
Say: "It has been inspired to me that a group of Jinn were listening." They said: "We have heard a magnificent Qur'an!"
72:2
"It guides to what is correct, so we believed in it, and we will not set up anyone with our Lord."
72:3
"And Exalted is the Majesty of our Lord, He has not taken a wife nor a son."
72:4
"And the foolish one among us used to say lies about God."
72:5
"And we had thought that neither mankind nor the Jinn would ever utter a lie against God."
72:6
"And there were men from among mankind who used to seek help from the men among the Jinn, but they only increased them in sin / rahaqan /fatigue, exhaustion."
6:112
And as such, We have permitted the enemies of every prophet-human and Jinn devils-to inspire each other with fancy words in order to deceive. Had your Lord willed, they would not have done it. You shall disregard them and their fabrications.
6:128
And the Day We gather them all: "O assembly of Jinn, you have managed to take many from mankind." Their supporters from mankind said: "Our Lord, we have indeed enjoyed one another, and we have reached our destiny to which You delayed us." He said: "The Fire is your dwelling, abiding therein, except as your Lord wishes." Your Lord is Wise, Knowledgeable.
6:130
"O assembly of Jinn and mankind, did not messengers come to you from amongst you and narrate to you My revelations, and warn you of the meeting of this Day?" They said: "Yes, we bear witness upon ourselves;" and the worldly life deceived them, and they bore witness upon themselves that they were rejecters.
7:38
He said: "Enter with the multitude of nations before you from mankind and Jinn to the Fire!" Every time a nation entered, it cursed its sister nation, until they are all gathered inside it; then the last of them says to the first: "Our Lord, these are the ones who have misguided us, so give them double the retribution of the Fire!" He replied: "Each will receive double, but you do not know."
7:179
And We have given to Hell many of the Jinn and mankind; they had hearts with which they did not understand, and they had eyes with which they did not see, and they had ears with which they did not hear. They are like hoofed animals; no, they are even more astray. These are the unaware ones.
18:50
And We said to the angels: "Yield to Adam." So they all yielded except for Satan. He was of the Jinn, he disobeyed the order of his Lord. Will you take him and his progeny as allies besides Me, while they are your enemy? Miserable for the transgressors is the substitute!
27:17
And the soldiers of Solomon were gathered, comprising of mankind and Jinn and birds, for they were to be spread out.
27:39
A powerful being from among the Jinn said: "I will bring it to you before you rise from your station. For I am strong and trustworthy."
34:12
And for Solomon the wind was given, traveling one month coming and one month going, and We caused a spring of tar to flow for him. And from among the Jinn are those that worked for him with the permission of his Lord; and any one of them who turns from Our commands, We shall cause him to taste the retribution of the Fire.
41:25
And We assigned to them associates who adorned their present and past actions-and the sentence was deserved by them-as it was for the nations before them of Jinn and mankind; they were losers.
41:29
And those who have rejected will say: "Our Lord, show us those who have misled us from among the Jinn and mankind so we can trample them under our feet, so that they would be the lowest."
46:18
These are the ones against whom the sentence has been deserved in nations who had come before them of mankind and Jinn; they are the losers.
46:29
And We dispatched to you a company of Jinn, in order to let them listen to the Qur'an. So when they arrived there, they said: "Pay attention." Then, when it was finished, they returned to their people, to warn them.
55:33
O assembly of Jinn and mankind, if you can penetrate the boundaries of the heavens and the earth, then go ahead and penetrate. You will not penetrate without might.
Peace
