An-Naml 27:84

حَتَّىٰٓ إِذَا جَآءُو قَالَ أَكَذَّبْتُم بِـَٔايَـٰتِى وَلَمْ تُحِيطُوا۟ بِهَا عِلْمًا أَمَّاذَا كُنتُمْ تَعْمَلُونَ

Ḥattā idhā jāū qāla akadhabtum biāyātī walam tuḥīṭū bihā ʿil'man ammādhā kuntum taʿmalūna

Until, when they arrive [at the place of Judgement], He will say, "Did you deny My signs while you encompassed them not in knowledge, or what [was it that] you were doing?"
