Surely (as for) those whom the angels cause to die while they are unjust to their souls, they shall say: In what state were you? They shall say: We were weak in the earth. They shall say: Was not Allah's earth spacious, so that you should have migrated therein? So these it is whose abode is hell, and it is an evil resort

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.
