Verse 18

وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ وَإِن تَدْعُ مُثْقَلَةٌ إِلَىٰ حِمْلِهَا لَا يُحْمَلْ مِنْهُ شَىْءٌ وَلَوْ كَانَ ذَا قُرْبَىٰٓ إِنَّمَا تُنذِرُ ٱلَّذِينَ يَخْشَوْنَ رَبَّهُم بِٱلْغَيْبِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَمَن تَزَكَّىٰ فَإِنَّمَا يَتَزَكَّىٰ لِنَفْسِهِۦ وَإِلَى ٱللَّهِ ٱلْمَصِيرُ

And no one carries another one’s sin. And if he calls for a load to be carried no one will carry it even if they are relatives. Surely, only those who fear their Lord in their privacy and observe the contact prayer will take heed. And whoever purifies himself, he only purifies his own soul. And to God is the ultimate return.
