Az-Zumar - 39:41

إِنَّا أَنزَلْنَا عَلَيْكَ الْكِتَابَ لِلنَّاسِ بِالْحَقِّ فَمَنِ اهْتَدَى فَلِنَفْسِهِ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا وَمَا أَنتَ عَلَيْهِم بِوَكِيلٍ
[39:41]
Surely We have revealed to you the Book with the truth for the sake of men; so whoever follows the right way, it is for his own soul and whoever errs, he errs only to its detriment; and you are not a custodian over them.
Verily We have revealed the Book to thee in Truth, for (instructing) mankind. He, then, that receives guidance benefits his own soul: but he that strays injures his own soul. Nor art thou set over them to dispose of their affairs.
Lo! We have revealed unto thee (Muhammad) the Scripture for mankind with truth. Then whosoever goeth right it is for his soul, and whosoever strayeth, strayeth only to its hurt. And thou art not a warder over them.
