Quran 29:14 from Surah Al-Ankaboot on Divine Marvels.
وَلَقَدۡ أَرۡسَلۡنَا نُوحًا إِلَىٰ قَوۡمِهِۦ فَلَبِثَ فِيهِمۡ أَلۡفَ سَنَةٍ إِلَّا خَمۡسِينَ عَامٗا فَأَخَذَهُمُ ٱلطُّوفَانُ وَهُمۡ ظَٰلِمُونَ
English translation: And verily We sent Nuh to his people and he remained among them a thousand year(s) save fifty year(s) then seized them the flood while they (were) wrongdoers
Transliteration: walaqad arsalna nuhan ila qawmihi falabitha fihim alfa sanatin illa khamsina aman fa-akhadhahumu al-tufanu wahum zalimuna
