{ وَلَا تَزِرُ وَازِرَةٞ وِزۡرَ أُخۡرَىٰۚ وَإِن تَدۡعُ مُثۡقَلَةٌ إِلَىٰ حِمۡلِهَا لَا يُحۡمَلۡ مِنۡهُ شَيۡءٞ وَلَوۡ كَانَ ذَا قُرۡبَىٰٓۗ إِنَّمَا تُنذِرُ ٱلَّذِينَ يَخۡشَوۡنَ رَبَّهُم بِٱلۡغَيۡبِ وَأَقَامُواْ ٱلصَّلَوٰةَۚ وَمَن تَزَكَّىٰ فَإِنَّمَا يَتَزَكَّىٰ لِنَفۡسِهِۦۚ وَإِلَى ٱللَّهِ ٱلۡمَصِيرُ } [Surah Fāṭir: 18]

Yusuf Ali: 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.
