Quran 27:84 from Surah An-Naml on Divine Marvels.
حَتَّىٰٓ إِذَا جَآءُو قَالَ أَكَذَّبۡتُم بِـَٔايَٰتِي وَلَمۡ تُحِيطُواْ بِهَا عِلۡمًا أَمَّاذَا كُنتُمۡ تَعۡمَلُونَ
English translation: Until when they come He will say Did you deny My Signs while not you encompassed them (in) knowledge or what you used (to) do
Transliteration: hatta idha jau qala akadhabtum biayati walam tuhitu biha il'man ammadha kuntum ta'maluna
