إِنَّا أَنزَلْنَا عَلَيْكَ الْكِتَابَ لِلنَّاسِ بِالْحَقِّ ۖ فَمَنِ اهْتَدَىٰ فَلِنَفْسِهِ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَا أَنتَ عَلَيْهِم بِوَكِيلٍ (41)
(39:41) (O Prophet), We revealed to you the Book with the Truth for all mankind. So he who follows the Right Way does so to his own benefit, and he who goes astray, shall hurt only himself by straying. You are not accountable on their behalf. *59
*59) That is, 'It is not for you to bring them to the Right Path. Your only duty is to present the Right Path before them. If they prefer to remain astray after that, you are not responsible for it."
