Verse 15

مَّنِ ٱهْتَدَىٰ فَإِنَّمَا يَهْتَدِى لِنَفْسِهِۦ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ وَمَا كُنَّا مُعَذِّبِينَ حَتَّىٰ نَبْعَثَ رَسُولًا

Anyone who is guided, then indeed his guidance benefits only him and anyone who has gone astray, then indeed his straying will only hurt him. No one will carry another one’s sins. And We do not make them suffer until We raise a messenger.
