Sahih Muslim 3031
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُطِيعٍ، حَدَّثَنَا هُشَيْمٌ، عَنْ أَبِي بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ قُلْتُ لاِبْنِ عَبَّاسٍ سُورَةُ التَّوْبَةِ قَالَ آلتَّوْبَةِ قَالَ بَلْ هِيَ الْفَاضِحَةُ مَا زَالَتْ تَنْزِلُ وَمِنْهُمْ وَمِنْهُمْ . حَتَّى ظَنُّوا أَنْ لاَ يَبْقَى مِنَّا أَحَدٌ إِلاَّ ذُكِرَ فِيهَا . قَالَ قُلْتُ سُورَةُ الأَنْفَالِ قَالَ تِلْكَ سُورَةُ بَدْرٍ . قَالَ قُلْتُ فَالْحَشْرُ قَالَ نَزَلَتْ فِي بَنِي النَّضِيرِ .
Sa'id ibn Jubayr said: I asked Ibn 'Abbas about Surat al-Tawbah. He said, “It is the surah of exposure. It kept being revealed with the words ‘among them’ and ‘among them,’ until they thought none of us would remain without being mentioned in it.” I asked him about Surat al-Anfal. He said, “That is the surah of Badr.” I asked about Surat al-Hashr. He said, “It was revealed about Banu al-Nadir.”
