Abu Juhaifa said, "I asked ʿAli, 'Have you got any book (which has been revealed to the Prophet ﷺ apart from the Qur'an)?' ʿAli replied, 'No, except Allah's Book or the power of understanding which has been bestowed (by Allah) upon a Muslim or what is (written) in this sheet of paper (with me).' Abu Juhaifa said, "I asked, 'What is (written) in this sheet of paper?' ʿAli replied, it deals with The Diyya (compensation (blood money) paid by the killer to the relatives of the victim), the ransom for the releasing of the captives from the hands of the enemies, and the law that no Muslim should be killed in Qisas (equality in punishment) for the killing of (a disbeliever).  

لاَ إِلاَّ كِتَابُ اللَّهِ أَوْ فَهْمٌ أُعْطِيَهُ رَجُلٌ مُسْلِمٌ أَوْ مَا فِي هَذِهِ الصَّحِيفَةِ قَالَ قُلْتُ فَمَا فِي هَذِهِ الصَّحِيفَةِ قَالَ الْعَقْلُ وَفَكَاكُ الأَسِيرِ وَلاَ يُقْتَلُ مُسْلِمٌ بِكَافِرٍ  

In the year of the Conquest of Mecca, the tribe of Khuzaʿa killed a man from the tribe of Bani Laith in revenge for a killed person, belonging to them. They informed the Prophet ﷺ about it. So he rode his Rahila (she-camel for riding) and addressed the people saying, "Allah held back the killing from Mecca. (The sub-narrator is in doubt whether the Prophet ﷺ said "elephant or killing," as the Arabic words standing for these words have great similarity in shape), but He (Allah) let His Apostle and the believers over power the infidels of Mecca. Beware! (Mecca is a sanctuary) Verily! Fighting in Mecca was not permitted for anyone before me nor will it be permitted for anyone after me. It (war) in it was made legal for me for few hours or so on that day. No doubt it is at this moment a sanctuary, it is not allowed to uproot its thorny shrubs or to uproot its trees or to pick up its Luqat (fallen things) except by a person who will look for its owner (announce it publicly). And if somebody is killed, then his closest relative has the right to choose one of the two-- the blood money (Diyya) or retaliation having the killer killed. In the meantime a man from Yemen came and said, "O Messenger of Allah ﷺ! Get that written for me." The Prophet ﷺ ordered his companions to write that for him. Then a man from Quraish said, "Except Al-Idhkhir (a type of grass that has good smell) O Messenger of Allah ﷺ, as we use it in our houses and graves." The Prophet ﷺ said, "Except Al-Idhkhir i.e. Al-Idhkhir is allowed to be plucked."  

أَنَّ خُزَاعَةَ قَتَلُوا رَجُلاً مِنْ بَنِي لَيْثٍ عَامَ فَتْحِ مَكَّةَ بِقَتِيلٍ مِنْهُمْ قَتَلُوهُ فَأُخْبِرَ بِذَلِكَ النَّبِيُّ ﷺ فَرَكِبَ رَاحِلَتَهُ فَخَطَبَ فَقَالَ إِنَّ اللَّهَ حَبَسَ عَنْ مَكَّةَ الْقَتْلَ أَوِ الْفِيلَ شَكَّ أَبُو عَبْدِ اللَّهِ وَسَلَّطَ عَلَيْهِمْ رَسُولَ اللَّهِ ﷺ وَالْمُؤْمِنِينَ أَلاَ وَإِنَّهَا لَمْ تَحِلَّ لأَحَدٍ قَبْلِي وَلاَ تَحِلُّ لأَحَدٍ بَعْدِي أَلاَ وَإِنَّهَا حَلَّتْ لِي سَاعَةً مِنْ نَهَارٍ أَلاَ وَإِنَّهَا سَاعَتِي هَذِهِ حَرَامٌ لاَ يُخْتَلَى شَوْكُهَا وَلاَ يُعْضَدُ شَجَرُهَا وَلاَ تُلْتَقَطُ سَاقِطَتُهَا إِلاَّ لِمُنْشِدٍ فَمَنْ قُتِلَ فَهُوَ بِخَيْرِ النَّظَرَيْنِ إِمَّا أَنْ يُعْقَلَ وَإِمَّا أَنْ يُقَادَ أَهْلُ الْقَتِيلِ فَجَاءَ رَجُلٌ مِنْ أَهْلِ الْيَمَنِ فَقَالَ اكْتُبْ لِي يَا رَسُولَ اللَّهِ فَقَالَ اكْتُبُوا لأَبِي فُلاَنٍ فَقَالَ رَجُلٌ مِنْ قُرَيْشٍ إِلاَّ الإِذْخِرَ يَا رَسُولَ اللَّهِ فَإِنَّا نَجْعَلُهُ فِي بُيُوتِنَا وَقُبُورِنَا فَقَالَ النَّبِيُّ ﷺ إِلاَّ الإِذْخِرَ إِلاَّ الإِذْخِرَ قَالَ أَبُو عَبْدِ اللَّهِ يُقَالُ يُقَادُ بِالْقَافِ فَقِيلَ لأَبِي عَبْدِ اللَّهِ أَىُّ شَىْءٍ كَتَبَ لَهُ قَالَ كَتَبَ لَهُ هَذِهِ الْخُطْبَةَ  

There is none among the companions of the Prophet ﷺ who has narrated more Hadiths than I except ʿAbdullah bin ʿAmr (bin Al-ʿAs) who used to write them and I never did the same.  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ مَا مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَحَدٌ أَكْثَرَ حَدِيثًا عَنْهُ مِنِّي إِلاَّ مَا كَانَ مِنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو فَإِنَّهُ كَانَ يَكْتُبُ وَلاَ أَكْتُبُ  

Ibn ʿAbbas said, "When the ailment of the Prophet ﷺ became worse, he said, 'Bring for me (writing) paper and I will write for you a statement after which you will not go astray.' But ʿUmar said, 'The Prophet is seriously ill, and we have got Allah's Book with us and that is sufficient for us.' But the companions of the Prophet ﷺ differed about this and there was a hue and cry. On that the Prophet ﷺ said to them, 'Go away (and leave me alone). It is not right that you should quarrel in front of me." Ibn ʿAbbas came out saying, "It was most unfortunate (a great disaster) that Messenger of Allah ﷺ was prevented from writing that statement for them because of their disagreement and noise. (Note: It is apparent from this Hadith that Ibn ʿAbbas had witnessed the event and came out saying this statement. The truth is not so, for Ibn ʿAbbas used to say this statement on narrating the Hadith and he had not witnessed the event personally. See Fath Al-Bari Vol. 1, p.220 footnote.) (See Hadith No. 228, Vol. 4).  

لَمَّا اشْتَدَّ بِالنَّبِيِّ ﷺ وَجَعُهُ قَالَ ائْتُونِي بِكِتَابٍ أَكْتُبُ لَكُمْ كِتَابًا لاَ تَضِلُّوا بَعْدَهُ قَالَ عُمَرُ إِنَّ النَّبِيَّ ﷺ غَلَبَهُ الْوَجَعُ وَعِنْدَنَا كِتَابُ اللَّهِ حَسْبُنَا فَاخْتَلَفُوا وَكَثُرَ اللَّغَطُ قَالَ قُومُوا عَنِّي وَلاَ يَنْبَغِي عِنْدِي التَّنَازُعُ فَخَرَجَ ابْنُ عَبَّاسٍ يَقُولُ إِنَّ الرَّزِيَّةَ كُلَّ الرَّزِيَّةِ مَا حَالَ بَيْنَ رَسُولِ اللَّهِ ﷺ وَبَيْنَ كِتَابِهِ
