﴿ وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَٰتُنَا بَيِّنَٰتٍۢ قَالَ ٱلَّذِينَ كَفَرُوا۟ لِلْحَقِّ لَمَّا جَآءَهُمْ هَٰذَا سِحْرٌۭ مُّبِينٌ ﴾

“But whenever Our messages are conveyed to them in all their clarity, they who are bent on denying the truth speak thus of the truth as soon as it is brought to them: “This is clearly nothing but spell­binding eloquence!””

And when Our signs the Qur’ān are recited to them namely to the people of Mecca being clear signs manifest signs bayyinātin is a circumstantial qualifier those who disbelieve from among them say of the truth that is the Qur’ān when it comes to them ‘This is plain sorcery!’ clear and evident sorcery.
