Surah 26. Ash-Shuara, Ayah 158

In my opinion, the specific message alluded to here relates, in the first instance, to the individual person's emotional reluctance to visualize the limited, transitory character of his own life on earth (hinted at in verses {146-149} above) and, hence, the judgment that awaits everyone in the life to come; and, secondly, to the element of compassion for all other living beings as a basis of true morality.
