﴿ 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 clear revelations) when the clear revelations of the Qur'an which explain the commands and prohibitions (are recited unto them) unto the disbelievers of Mecca, (those who disbelieve) the disbelievers of Mecca (say of the Truth) of the Qur'an (when it reacheth them) when the Prophet (pbuh) came to them: (This is mere magic) this is a manifest lie.
