Surah Al-Ankabut (The Spider), Verse 14

وَلَقَدْ اَرْسَلْنَا نُوْحًا اِلٰی قَوْمِهٖ فَلَبِثَ فِیْهِمْ اَلْفَ سَنَةٍ اِلَّا خَمْسِیْنَ عَامًا فَاَخَذَهُمُ الطُّوْفَانُ وَهُمْ ظٰلِمُوْنَ ۟

Wa laqad arsalnaa Noohan ilaa qawmihee falabisa feehim alfa sanatin illaa khamseena 'aaman fa akhazahumut toofaanu wa hum zaalimoon

“We (once) sent Noah to his people, and he tarried among them a thousand years less fifty: but the Deluge overwhelmed them while they (persisted in) sin.”
