Narrated Ibn 'Abbas:

"I said to 'Uthman bin 'Affan: 'What was your reasoning with Al-Anfal - while it is from the Muthani (Surah with less than one-hundred Ayat), and Bara'ah while it is from the Mi'in (Surah with about one-hundred Ayat), then you put them together, without writing the line Bismillahir-Rahmanir-Rahim between them, and you placed them with the seven long (Surah) - why did you do that?' So 'Uthman said: 'A long time might pass upon the Messenger of Allah ﷺ without anything being revealed to him, and then sometimes a Surah with numerous (Ayat) might be revealed. So when something was revealed, he would call for someone who could write, and say: "Put these Ayat in the Surah which mentions this and that in it." When an Ayah was revealed, he would say: "Put this Ayah in the Surah which mentions this and that in it." Now Al-Anfal was among the first of those revealed in Al-Madinah, and Bara'ah among the last of those revealed of the Qur'an, and its narrations (those of Bara'ah) resembled its narrations (those of Al-Anfal), so we thought that it was part of it. Then the Messenger of Allah ﷺ died, and it was not made clear to us whether it was part of it. So it is for this reason that we put them together without writing Bismillahir-Rahmanir-Rahim between them, and we put that with the seven long (Surahs).'"

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَمُحَمَّدُ بْنُ جَعْفَرٍ، وَابْنُ أَبِي عَدِيٍّ، وَسَهْلُ بْنُ يُوسُفَ، قَالُوا حَدَّثَنَا عَوْفُ بْنُ أَبِي جَمِيلَةَ، حَدَّثَنَا يَزِيدُ الْفَارِسِيُّ، حَدَّثَنَا ابْنُ عَبَّاسٍ، قَالَ قُلْتُ لِعُثْمَانَ بْنِ عَفَّانَ مَا حَمَلَكُمْ أَنْ عَمَدْتُمْ، إِلَى الأَنْفَالِ وَهِيَ مِنَ الْمَثَانِي وَإِلَى بَرَاءَةَ وَهِيَ مِنَ الْمِئِينَ فَقَرَنْتُمْ بَيْنَهُمَا وَلَمْ تَكْتُبُوا بَيْنَهُمَا سَطْرَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ وَوَضَعْتُمُوهُمَا فِي السَّبْعِ الطُّوَلِ مَا حَمَلَكُمْ عَلَى ذَلِكَ فَقَالَ عُثْمَانُ كَانَ رَسُولُ اللَّهِ ﷺ مِمَّا يَأْتِي عَلَيْهِ الزَّمَانُ وَهُوَ تَنْزِلُ عَلَيْهِ السُّوَرُ ذَوَاتُ الْعَدَدِ فَكَانَ إِذَا نَزَلَ عَلَيْهِ الشَّىْءُ دَعَا بَعْضَ مَنْ كَانَ يَكْتُبُ فَيَقُولُ ضَعُوا هَؤُلاَءِ الآيَاتِ فِي السُّورَةِ الَّتِي يُذْكَرُ فِيهَا كَذَا وَكَذَا وَإِذَا نَزَلَتْ عَلَيْهِ الآيَةُ فَيَقُولُ ضَعُوا هَذِهِ الآيَةَ فِي السُّورَةِ الَّتِي يُذْكَرُ فِيهَا كَذَا وَكَذَا وَكَانَتِ الأَنْفَالُ مِنْ أَوَائِلِ مَا أُنْزِلَتْ بِالْمَدِينَةِ وَكَانَتْ بَرَاءَةُ مِنْ آخِرِ الْقُرْآنِ وَكَانَتْ قِصَّتُهَا شَبِيهَةً بِقِصَّتِهَا فَظَنَنْتُ أَنَّهَا مِنْهَا فَقُبِضَ رَسُولُ اللَّهِ ﷺ وَلَمْ يُبَيِّنْ لَنَا أَنَّهَا مِنْهَا فَمِنْ أَجْلِ ذَلِكَ قَرَنْتُ بَيْنَهُمَا وَلَمْ أَكْتُبْ بَيْنَهُمَا سَطْرَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ فَوَضَعْتُهَا فِي السَّبْعِ الطُّوَلِ .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ عَوْفٍ عَنْ يَزِيدَ الْفَارِسِيِّ عَنِ ابْنِ عَبَّاسٍ . وَيَزِيدُ الْفَارِسِيُّ قَدْ رَوَى عَنِ ابْنِ عَبَّاسٍ غَيْرَ حَدِيثٍ وَيُقَالُ هُوَ يَزِيدُ بْنُ هُرْمُزَ وَيَزِيدُ الرَّقَاشِيُّ هُوَ يَزِيدُ بْنُ أَبَانَ الرَّقَاشِيُّ وَلَمْ يُدْرِكِ ابْنَ عَبَّاسٍ إِنَّمَا رَوَى عَنْ أَنَسِ بْنِ مَالِكٍ وَكِلاَهُمَا مِنَ التَّابِعِينَ مِنْ أَهْلِ الْبَصْرَةِ وَيَزِيدُ الْفَارِسِيُّ أَقْدَمُ مِنْ يَزِيدَ الرَّقَاشِيِّ .
