Satan made them stumble upon it and he made them expel from the state both they had been living; and We said: “You Get down as some of you are enemies to others, and in the earth, you will have a resting place and a livelihood for a while”.
The banned tree or banned fruit in Paradise is the sexual intercourse that is prohibited in Paradise. It is told in verses 20: 117-119 that there is no hunger, thirst, nakedness, fatigue, temperature, etc. in Paradise. The Impartial Lord can’t send anyone to Hell without any reason. That is why He gave Satan all powers to deviate mankind from the Straightpath. Satan obstructs mankind, not from the Arabic Quran, but Adhikr as told in verse 25: 29. When Adam and Eve intended for sexual intercourse by the temptation of Satan and when they rubbed their pubic hairs with each other, sexual organs appeared for them which they didn’t have before, and thus they became naked. And they became unjust by disobeying the Lord. It is warned through verse 7: 27: "Oh you children of Adam! You don’t let Satan tempt you just as he turned two of your ancestors out of Paradise by removing their ‘clothing of heedfulness’ to show them their private parts, he and his tribe watch you from where you don’t see them. We have placed devils as patrons for those who don’t believe”.
It is told both in verses 41: 28 and 63: 4 that the hypocrites are the enemies of the Lord and the believers. It is told in verse 32: 18: “Is the believer just like the hypocritical transgressors? No, they are not equal”. It is told in both verses 6: 112 and 114: 6 that there are Satans in men and Jinns. It is told in verse 25: 31 that the hypocrites and their blind followers are enemies to all Prophets and believers. So among the Arabic Quran reading Fujjar who didn’t change his Jinn soul-mate mentioned in verses 43: 36-39 into a believer with Adhikr, he is a Kafir, and he will return into the Hell which is Satan’s house. See explanation 2: 11-12; 7: 37 and 4: 150-151.
