﴿ ۞ أَلَمْ أَعْهَدْ إِلَيْكُمْ يَٰبَنِىٓ ءَادَمَ أَن لَّا تَعْبُدُوا۟ ٱلشَّيْطَٰنَ ۖ إِنَّهُۥ لَكُمْ عَدُوٌّۭ مُّبِينٌۭ ﴾

“Did I not enjoin on you, O you children of Adam, that you should not worship Satan – since, verily, he is your open foe”

In the present life, good people and bad people live in the same world. But in the life of the Hereafter, these two groups will be separated; the followers of Satan will be with Satan and the subjects of the Most Beneficent God will be with God. Nobody worships Satan per se, but the worshipper of anybody other than God is in fact indirectly the worshipper of Satan.
