Surah Al-Jathiyah (The Kneeling), Verse 24

وَقَالُوْا مَا هِیَ اِلَّا حَیَاتُنَا الدُّنْیَا نَمُوْتُ وَنَحْیَا وَمَا یُهْلِكُنَاۤ اِلَّا الدَّهْرُ وَمَا لَهُمْ بِذٰلِكَ مِنْ عِلْمٍ اِنْ هُمْ اِلَّا یَظُنُّوْنَ ۟

Wa qaaloo maa hiya illaa hayaatunad dunyaa namootu wa nahyaa wa maa yuhlikunaaa illad dahr; wa maa lahum bizaalika min 'ilmin in hum illaayazunnoon

“And they say: "What is there but our life in this world? We shall die and we live, and nothing but time can destroy us." But of that they have no knowledge: they merely conjecture:”
