The chapter takes its title from the first verse which begins with the distraction from reality that the competition of wanting more wealth and children does. Historically it referred to the clans of the Quraysh who competing with each other even counted their dead to prove that they were greater in the size of their clans.
The first two verses speak of the delusion of hoarding wealth whilst the remaining verses promise that those who persist in such behaviour will bear the consequences of the fire with certainty.
