Quran 11:8 from Surah Hud on Divine Marvels.
وَلَئِنۡ أَخَّرۡنَا عَنۡهُمُ ٱلۡعَذَابَ إِلَىٰٓ أُمَّةٖ مَّعۡدُودَةٖ لَّيَقُولُنَّ مَا يَحۡبِسُهُۥٓۗ أَلَا يَوۡمَ يَأۡتِيهِمۡ لَيۡسَ مَصۡرُوفًا عَنۡهُمۡ وَحَاقَ بِهِم مَّا كَانُواْ بِهِۦ يَسۡتَهۡزِءُونَ
English translation: And if We delay from them the punishment for a time determined they will surely say What detains it No doubt (On) the Day it comes to them not (will be) averted from them and will surround them what they used (to) mock at [it] mock at [it]
Transliteration: wala-in akharna anhumu al-'adhaba ila ummatin ma'dudatin layaqulunna ma yahbisuhu ala yawma yatihim laysa masrufan anhum wahaqa bihim ma kanu bihi yastahziuna
