Divine protection of believers

إِنَّ عِبَادِى لَيْسَ لَكَ عَلَيْهِمْ سُلْطَـٰنٌ إِلَّا مَنِ ٱتَّبَعَكَ مِنَ ٱلْغَاوِينَ

Indeed, My servants - no authority will you have over them, except those who follow you of the deviators.

وَٱضْرِبْ لَهُم مَّثَلًا أَصْحَـٰبَ ٱلْقَرْيَةِ إِذْ جَآءَهَا ٱلْمُرْسَلُونَ

And present to them an example: the people of the city, when the messengers came to it -

مَآ أَنتُمْ عَلَيْهِ بِفَـٰتِنِينَ

You cannot tempt [anyone] away from Him
