Emusan:
I'll use the stone of this surah to kill two birds but I want the readers to have the following in mind as s/he reads through this article.
1) That Quran itself testifies that before Adam and Eve sinned they were living in PARADISE not on Earth.
2) That this conversation between Allah and Satan (Iblis) took place BEFORE Adam and Eve eventually SINNED.

Now in Allah’s command to the angels to bow down to Adam shortly after Adam was created, and what happened after that, is very interested to consider. This story was repeated at least seven times in the Qu’ran which can be found in Surah 2, 7, 15, 17, 18, 20, and 38.

But let me quote only Surah 15:35-37, 39.

35 "And the curse shall be on thee till the Day of Judgment."
36 (Iblis) said: "O my Lord! Give me then respite till the Day the (dead) are raised."
37 (Allah) said: "Respite is granted thee…
39 “…I will make (wrong) fair-seeming to them on the earth, and I will put them all in the wrong Y. Ali

Satan seems to know the unseen!
Here we see Allah talking about "The Day of Judgement," (When Adam and Eve were just created without sin or ever sinned) though one can say well it’s because Allah is All-knowing but the next statement by Satan is alarming, why? We see Satan talking about “The Day the (DEAD) are raised”, really!
How come Satan knows that there will be RESURRECTION of the dead when DEATH has not even occurred nor the event that leads to death had happened? In fact Satan reinforced his statement by saying “I will make (wrong) fair-seeming to THEM ON EARTH”. ON EARTH!!! How come? Does Satan actually know that Adam and Eve will sin and cast out from PARADISE to EARTH? Whereas Allah said this angels don't know what he knows.

Satan was led astray by Allah
In the same Surah I quoted above verse 39 reads “(Iblis) said: ‘O my Lord! Because Thou hast put me in the wrong,…’” Y. Ali

We see here that Allah led Satan astray.
Well if this translation seems not be cleared enough let’s see how other translations rendered this particular statement.

“He said: My Lord! Because Thou hast made life evil to me,...” M. Habib Shakir
“He said: My Lord! Because Thou hast sent me astray,…” M. Pickthall
“Iblis (Satan)] said: "O my Lord! Because you misled me,…” Mohsin Khan.
“He said 'O my Lord, I swear of that. You led me astray,…” Ahadees

The question one can ask is, how did Allah mislead Satan? Well Quran itself seems to have the answer when it says ONLY ALLAH should be bowing to NO other being, so Satan actually obeying the word of Allah but unfortunately Satan has to get the reward for his obedient by being cast out from paradise.

(Satan be like, since we’re being told that NO Being should be bowing to except Allah, this one now to bow for Adam again might be a test from Allah to know who will fall victim let me quickly obey the first instruction.)

Allah is the creator of evil and good :
https://quran.com/search?q=Allah%20guides%20whom%20He%20wills
so you can say He can lead people astray and guide those whom He like...
Allah gave Iblis a change (forgiveness) untill the day of judgement BUT he will refuse it (bow down to the grave of Adam)
Allah give you everything so it is easy for Him to take everything that you have (including the air that you inhale)
so why Allah let the Iblis do what he does ? (because that already His master plan of the course of humanity and Jinns life)
to see whoever that are loyal or faithfull enough to get pass His test in this life...may we all be at His mercy, Amen....
