حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، رضى الله عنهما ‏ Begin hadith 7‏ 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. Translation Not Available
