Surah Al-Ahqaf 46:7

وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَـٰتُنَا بَيِّنَـٰتٍ قَالَ ٱلَّذِينَ كَفَرُوا۟ لِلْحَقِّ لَمَّا جَآءَهُمْ هَـٰذَا سِحْرٌ مُّبِينٌ

And when Our verses are recited to them as clear evidences, those who disbelieve say of the truth when it has come to them, "This is obvious magic."

Translation: Saheeh International
