The Statement of Allah "Who have made the Qur'an into parts (i.e., believed in one part and disbelieved in the other) ." (V.15:91)
حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، رضى الله عنهما {الَّذِينَ جَعَلُوا الْقُرْآنَ عِضِينَ} قَالَ هُمْ أَهْلُ الْكِتَابِ، جَزَّءُوهُ أَجْزَاءً، فَآمَنُوا بِبَعْضِهِ وَكَفَرُوا بِبَعْضِهِ.
Narrated Ibn `Abbas: Those who have made their Scripture into parts are the people of the Scripture who divided it into portions and believed in a part of it and disbelieved the other.
