At-Takathur, "Competition in Increase," is the hundred-and-second surah — 8 verses revealed in Mecca.1
What it is about
The whole surah is a single warning: "Competition in [worldly] increase diverts you until you visit the graveyards. No! You are going to know. Then, no! You are going to know. No! If you only knew with knowledge of certainty... You will surely see the Hellfire. Then you will surely see it with the eye of certainty. Then you will surely be asked that Day about pleasure."2
The Prophet ﷺ once recited it and then said, "The son of Adam claims: My wealth, my wealth," and asked whether a person truly owns anything except what they eat and use up, wear out, or give in charity and so send ahead.3
Why it matters
At-Takathur speaks to a very human habit: measuring life by having more than others. It warns that this race can fill a whole life until the grave interrupts it, and that every pleasure enjoyed will be asked about. It moves from "knowledge of certainty" to "the eye of certainty" — from knowing a truth to seeing it — and the Prophet's ﷺ comment makes the lesson plain: what a person keeps is what they gave away.
