Anti-Hadith Hadith
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.
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 أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا مُطَرِّفٌ، أَنَّ عَامِرًا، حَدَّثَهُمْ عَنْ أَبِي جُحَيْفَةَ ـ رضى الله عنه ـ قَالَ قُلْتُ لِعَلِيٍّ ـ رضى الله عنه هَلْ عِنْدَكُمْ شَىْءٌ مِنَ الْوَحْىِ إِلاَّ مَا فِي كِتَابِ اللَّهِ قَالَ وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ مَا أَعْلَمُهُ إِلاَّ فَهْمًا يُعْطِيهِ اللَّهُ رَجُلاً فِي الْقُرْآنِ، وَمَا فِي هَذِهِ الصَّحِيفَةِ. قُلْتُ وَمَا فِي الصَّحِيفَةِ قَالَ الْعَقْلُ وَفَكَاكُ الأَسِيرِ، وَأَنْ لاَ يُقْتَلَ مُسْلِمٌ بِكَافِرٍ.
Narrated Abu Juhaifa: I asked Ali, "Do you have the knowledge of any Divine Inspiration besides what is in Allah's Book?" Ali replied, "No, by Him Who splits the grain of corn and creates the soul. I don't think we have such knowledge, but we have the ability of understanding which Allah may endow a person with, so that he may understand the Qur'an, and we have what is written in this paper as well." I asked, "What is written in this paper?" He replied, "The understanding, releasing of the captive, and that a Muslim should not be killed by a disbeliever.
