﴿ 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 patron by obeying him and those who ascribe partners to Him that is to God.
