Faatir 35:18

No bearer of burdens can bear the burden of another. If a heavily-laden soul calls for help to bear its burden, nothing of it will be carried, even if he is a close relative. You can only warn those who fear their Lord unseen[6] and establish prayer. Whoever purifies himself, he only does so for his own benefit. To Allah is the final return.

[6] Without seeing Him or when they are in private.

And no bearer of burdens will bear the burden of another. And if a heavily laden soul calls [another] to [carry some of] its load, nothing of it will be carried, even if he should be a close relative. You can only warn those who fear their Lord unseen and have established prayer. And whoever purifies himself only purifies himself for [the benefit of] his soul. And to Allāh is the [final] destination.

18. And no bearer of burdens shall bear another’s burden; and if one heavily laden calls another to (bear) his load, nothing of it will be lifted even though he be near of kin. You (O Muhammad صلى الله عليه وسلم) can warn only those who fear their Lord unseen and perform As-Salât (Iqâmat-as-Salât). And he who purifies himself (from all kinds of sins), then he purifies only for the benefit of his ownself. And to Allâh is the (final) Return (of all).

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.
