Surah Al-Jathiyah, Verse 24

وَقَالُواْ مَا هِيَ إِلَّا حَيَاتُنَا ٱلدُّنۡيَا نَمُوتُ وَنَحۡيَا وَمَا يُهۡلِكُنَآ إِلَّا ٱلدَّهۡرُۚ وَمَا لَهُم بِذَٰلِكَ مِنۡ عِلۡمٍۖ إِنۡ هُمۡ إِلَّا يَظُنُّونَ٢٤

waqālū mā hiya illā ḥayātunā l-dun'yā namūtu wanaḥyā wamā yuh'likunā illā l-dahru wamā lahum bidhālika min ʿil'min in hum illā yaẓunnūna

And they say, "There is not but our worldly life; we die and live, and nothing destroys us except time." And they have of that no knowledge; they are only assuming.
