Az-Zumar 39:41

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

Innā anzalnā ʿalayka l-kitāba lilnnāsi bil-ḥaqi famani ih'tadā falinafsihi waman ḍalla fa-innamā yaḍillu ʿalayhā wamā anta ʿalayhim biwakīlin

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.
