حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ ثَابِتٍ الْمَرْوَزِيُّ، حَدَّثَنِي عَلِيُّ بْنُ حُسَيْنٍ، عَنْ أَبِيهِ، عَنْ يَزِيدَ النَّحْوِيِّ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ ‏{‏ فَكُلُوا مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ ‏}‏ ‏{‏ وَلاَ تَأْكُلُوا مِمَّا لَمْ يُذْكَرِ اسْمُ اللَّهِ عَلَيْهِ ‏}‏ فَنُسِخَ وَاسْتَثْنَى مِنْ ذَلِكَ فَقَالَ ‏{‏ وَطَعَامُ الَّذِينَ أُوتُوا الْكِتَابَ حِلٌّ لَكُمْ وَطَعَامُكُمْ حِلٌّ لَهُمْ ‏}‏ ‏.‏

Narrated Ibn 'Abbas: The verse: "So eat of (meats) on which Allah's name hath been pronounced" and the verse: "Eat not of (meats) on which Allah's name hath not been pronounced" were abrogated, meaning an exception was made therein by the verse: "The food of the people of the Book is lawful unto you and yours is lawful unto them."
