"And among them are those who believe in it, and among them are those who do not believe in it," meaning: and among the polytheists are those who will eventually believe in the Quran, and among them are those who will not believe in it. "And your Lord is most knowing of the corrupters."
﴿وَمِنْهُمْ مَنْ يُؤْمِنُ بِهِ وَمِنْهُمْ من لَا يُؤمن بِهِ﴾ أَيْ: وَمِنَ الْمُشْرِكِينَ مَنْ سَيُؤْمِنُ بِالْقُرْآنِ، وَمِنْهُمْ مَنْ لَا يُؤْمِنُ بِهِ ﴿وَرَبُّكَ أَعْلَمُ بِالْمُفْسِدِينَ﴾.
