Quran 30:43 — The Romans (Al-Room)

Therefore, you shall devote yourself completely to this perfect religion, before a day comes which is made inevitable by GOD. On that day, they will be shocked.

[30:42] Say, "Roam the earth and note the consequences for those before you." Most of them were idol worshipers.

[30:44] Whoever disbelieves, disbelieves to the detriment of his own soul, while those who lead a righteous life, do so to strengthen and develop their own souls.
