Az Zumar Ayah 41

إِنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَـٰبَ لِلنَّاسِ بِٱلْحَقِّ‌ۖ فَمَنِ ٱهْتَدَىٰ فَلِنَفْسِهِۦ‌ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا‌ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ ٤١ Surely We have revealed to you the Book ?O Prophet? with the truth for humanity. So whoever chooses to be guided, it is for their own good. And whoever chooses to stray, it is only to their own loss. You are not a keeper over them.
