Sura at-Takathur discusses the central theme of how worldly competition causes people to forget about the hereafter. It warns that one day people will be questioned about how they spent their lives accumulating wealth and pleasures instead of preparing for the afterlife. The surah asserts that rivalries over material gains will not benefit anyone on the Day of Judgment. It urges focusing less on piling up wealth and more on righteous deeds, as worldly possessions cannot be taken to the afterlife.
