And no bearer of burdens shall bear

[35:18] 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 SAW) can warn only those who fear their Lord unseen, and perform As-Salat (IqamatasSalat). And he who purifies himself (from all kinds of sins), then he purifies only for the benefit of his ownself. And to Allah is the (final) Return (of all).

And no burdened soul can bear another's burden) i.e. with a good disposition of the soul but only insofar as it is forced to do so; it is also said that this means: no soul will be taken to task for the crime of another; and it is also said that this means: no soul will be tormented without having committed a crime, (and if one heavy laden) with sins (crieth for (help with) his load, naught of it) none of the sins (will be lifted even though he (unto whom he crieth) be of kin) his father, mother, son or daughter. (Thou warnest only) your warning, O Muhammad, benefits only (those who fear their Lord in secret) those who work for their Lord even though He is invisible to them, but nothing is invisible to Him, (and have established worship) and perform the five daily prayers. (He who groweth (in goodness)) he who believes in Allah's divine Oneness, does good works and spends of his wealth in charity, (groweth only for himself) the reward of all this goes to his own soul. (Unto Allah is the journeying) unto Allah is the return in the Hereafter.
