حَدَّثَنَا ابْنُ مُبَشِّرٍ ، ثنا أَحْمَدُ بْنُ سِنَانٍ ، ثنا ابْنُ مَهْدِيٍّ ، ثنا سُفْيَانُ ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ ، عَنْ طَلْحَةَ بْنِ عَبْدِ اللَّهِ بْنِ عَوْفٍ ، قَالَ : " صَلَّى ابْنُ عَبَّاسٍ عَلَى جِنَازَةٍ فَقَرَأَ بِ فَاتِحَةِ الْكِتَابِ ، فَقُلْتُ لَهُ ، فَقَالَ : إِنَّهُ مِنَ السُّنَّةِ ، أَوْ مِنْ تَمَامِ السُّنَّةِ " .
Talhah bin Abdullah (may Allah have mercy on him) narrates: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) led a funeral prayer, and he recited Surah Al-Fatihah in it. I asked him about this, and he said: This is Sunnah. (The narrator is in doubt, perhaps these are the words:) The complete Sunnah is this.
