﴿ إِنَّمَا سُلْطَٰنُهُۥ عَلَى ٱلَّذِينَ يَتَوَلَّوْنَهُۥ وَٱلَّذِينَ هُم بِهِۦ مُشْرِكُونَ ﴾

“he has power only over those who are willing to follow him, and who [thus] ascribe to him a share in God's divinity.”

His [Satan's] power is only over those who choose him as [their] ally, at the station of the soul by virtue of the correspondence that is between them in terms of darkness and impurity, since the adoption of an ally is dictated by the genus-correspondence [between a person and his ally], and those who associate him [with God], by attributing power and effect to him, nay by obeying him and complying with his commands by virtue of the alliance mentioned [above].
