Sura al-Faṭīr 35:18

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 ٱللَّـهِ ٱلْمَصِيرُ

wa-lā taziru wāziratun wizra ukhrā wa-in tadʿu muthqalatun ilā ḥimlihā lā yuḥmal minhu shayʾun wa-law kāna dhā qurba innamā tundhiru lladhīna yakhshawna rabbahum bil-ghaybi wa-aqāmū l-ṣalāta wa-man tazakkā fa-innamā yatazakka li-nafsihi wa-ilā allāhi l-maṣīru

Nor can a bearer of burdens bear another's burdens if one heavily laden should call another to (bear) his load. Not the least portion of it can be carried (by the other). Even though he be nearly related. Thou canst but admonish such as fear their Lord unseen and establish regular Prayer. And whoever purifies himself does so for the benefit of his own soul; and the destination (of all) is to Allah.
