Why God doesn't stop satan?

[WinterHold]

It is said in the bible that satan "roams the earth and seeks who to devour". Meaning, they end up in hell. Why God doesn't stop this madness? What is he waiting for?

According to Islam, God is the creator of Satan, and the maker of this scenario we are living.
He knew that Satan would rebel even before he made him.

Look at this Quranic verses:

Sura 2, The Quran:
https://quran.ksu.edu.sa/index.php?l=en#...rans=en_sh

( 35 )   And We said, "O Adam, dwell, you and your wife, in Paradise and eat therefrom in [ease and] abundance from wherever you will. But do not approach this tree, lest you be among the wrongdoers."

( 36 )   But Satan caused them to slip out of it and removed them from that [condition] in which they had been. And We said, "Go down, [all of you], as enemies to one another, and you will have upon the earth a place of settlement and provision for a time."

( 37 )   Then Adam received from his Lord [some] words, and He accepted his repentance. Indeed, it is He who is the Accepting of repentance, the Merciful.

This life is a mere test against Satan. Why would God stop the main problem in our test?
Satan will always exist in this life, and our whole life is "a battle against him".

So the question doesn't make any sense according to Islam's message.
