Qur'an 39:41 · Az-Zumar

إِنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَٰبَ لِلنَّاسِ بِٱلْحَقِّ ۖ فَمَنِ ٱهْتَدَىٰ فَلِنَفْسِهِۦ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ

(41) Indeed, We sent down to you the Book for the people in truth. So whoever is guided - it is for [the benefit of] his soul; and whoever goes astray only goes astray to its detriment. And you are not a manager [i.e., authority] over them.
