Sahih al-Bukhari 5019
Narrated `Abdul `Aziz bin Rufai':
Shaddad bin Ma'qil and I entered upon Ibn `Abbas. Shaddad bin Ma'qil asked him, "Did the Prophet (ﷺ) 
leave anything (besides the Qur'an)?" He replied. "He did not leave anything except what is Between 
the two bindings (of the Qur'an)." Then we visited Muhammad bin Al-Hanafiyya and asked him (the 
same question). He replied, "The Prophet (ﷺ) did not leave except what is between the bindings (of the 
Qur'an).
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الْعَزِيزِ بْنِ رُفَيْعٍ، قَالَ دَخَلْتُ أَنَا وَشَدَّادُ بْنُ مَعْقِلٍ، عَلَى ابْنِ عَبَّاسٍ رضى الله عنهما فَقَالَ لَهُ شَدَّادُ بْنُ مَعْقِلٍ أَتَرَكَ النَّبِيُّ صلى الله عليه وسلم مِنْ شَىْءٍ قَالَ مَا تَرَكَ إِلاَّ مَا بَيْنَ الدَّفَّتَيْنِ‏.‏ قَالَ وَدَخَلْنَا عَلَى مُحَمَّدِ ابْنِ الْحَنَفِيَّةِ فَسَأَلْنَاهُ فَقَالَ مَا تَرَكَ إِلاَّ مَا بَيْنَ الدَّفَّتَيْنِ‏.‏
