16:100
إِنَّمَا سُلْطَـٰنُهُۥ عَلَى ٱلَّذِينَ يَتَوَلَّوْنَهُۥ وَٱلَّذِينَ هُم بِهِۦ مُشْرِكُونَ
innamā sul'ṭānuhu ʿalā alladhīna yatawallawnahu wa-alladhīna hum bihi mush'rikūna
his power is only over those who ally themselves with him and those who, because of him, join partners with God.
His power is only over those who obey and follow him (Satan), and those who join partners with Him (Allâh i.e. those who are Mushrikûn i.e. polytheists. See Verse 6:121).
