Quran 17:15 Al-Isra, ayah 15 of 111

مَّنِ ٱهْتَدَىٰ فَإِنَّمَا يَهْتَدِى لِنَفْسِهِۦ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۚ وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ ۗ وَمَا كُنَّا مُعَذِّبِينَ حَتَّىٰ نَبْعَثَ رَسُولًا ۝١٥

17:15 Whosoever goeth right, it is only for (the good of) his own soul that he goeth right, and whosoever erreth, erreth only to its hurt. No laden soul can bear another's load, We never punish until we have sent a messenger.
