Fatir - 35:18

وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَى وَإِن تَدْعُ مُثْقَلَةٌ إِلَى حِمْلِهَا لَا يُحْمَلْ مِنْهُ شَيْءٌ وَلَوْ كَانَ ذَا قُرْبَى إِنَّمَا تُنذِرُ الَّذِينَ يَخْشَوْنَ رَبَّهُم بِالغَيْبِ وَأَقَامُوا الصَّلَاةَ وَمَن تَزَكَّى فَإِنَّمَا يَتَزَكَّى لِنَفْسِهِ وَإِلَى اللَّهِ الْمَصِيرُ
[35:18]
And a burdened soul cannot bear the burden of another and if one weighed down by burden should cry for (another to carry) its burden, not aught of it shall be carried, even though he be near of kin. You warn only those who fear their Lord in secret and keep up prayer; and whoever purifies himself, he purifies himself only for (the good of) his own soul; and to Allah is the eventual coming.
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.
And no burdened soul can bear another's burden, and if one heavy laden crieth for (help with) his load, naught of it will be lifted even though he (unto whom he crieth) be of kin. Thou warnest only those who fear their Lord in secret, and have established worship. He who groweth (in goodness), groweth only for himself, (he cannot by his merit redeem others). Unto Allah is the journeying.
