وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَٰتُنَا بَيِّنَٰتٍۢ قَالُوا۟ مَا هَٰذَآ إِلَّا رَجُلٌۭ يُرِيدُ أَن يَصُدَّكُمْ عَمَّا كَانَ يَعْبُدُ ءَابَآؤُكُمْ وَقَالُوا۟ مَا هَٰذَآ إِلَّآ إِفْكٌۭ مُّفْتَرًۭى ۚ وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لِلْحَقِّ لَمَّا جَآءَهُمْ إِنْ هَٰذَآ إِلَّا سِحْرٌۭ مُّبِينٌۭ
And if Our revelations are recited unto them in plain terms, they say: This is naught else than a man who would turn you away from what your fathers used to worship; and they say: This is naught else than an invented lie. Those who disbelieve say of the truth when it reacheth them: This is naught else than mere magic.
Surah Saba(34:43)
