Satan's Limited Power

إِنَّ عِبَادِى لَيْسَ لَكَ عَلَيْهِمْ سُلْطَـٰنٌ ۚ وَكَفَىٰ بِرَبِّكَ وَكِيلًا

Indeed, over My [believing] servants there is for you no authority. And sufficient is your Lord as Disposer of affairs.

إِنَّمَا ٱلنَّجْوَىٰ مِنَ ٱلشَّيْطَـٰنِ لِيَحْزُنَ ٱلَّذِينَ ءَامَنُوا۟ وَلَيْسَ بِضَآرِّهِمْ شَيْـًٔا إِلَّا بِإِذْنِ ٱللَّهِ ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

Private conversation is only from Satan that he may grieve those who have believed, but he will not harm them at all except by permission of Allāh. And upon Allāh let the believers rely.
