Narrated `Aisha: Allah’s Messenger (ﷺ) came to me and I told him about the slave-girl (Barirah) Allah’s Messenger (ﷺ) said, “Buy and manumit her, for the Wala is for the one who manumits.” In the evening the Prophet (ﷺ) got up and glorified Allah as He deserved and then said, “Why do some people impose conditions which are not present in Allah’s Book? Whoever imposes such a condition as is not in Allah’s Laws, then that condition is invalid even if he imposes one hundred conditions, for Allah’s conditions are more binding and reliable.”
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ عُرْوَةُ بْنُ الزُّبَيْرِ قَالَتْ عَائِشَةُ ـ رضى الله عنها دَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَذَكَرْتُ لَهُ، فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ” اشْتَرِي وَأَعْتِقِي، فَإِنَّ الْوَلاَءَ لِمَنْ أَعْتَقَ ”. ثُمَّ قَامَ النَّبِيُّ صلى الله عليه وسلم مِنَ الْعَشِيِّ، فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ، ثُمَّ قَالَ ” مَا بَالُ أُنَاسٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَ فِي كِتَابِ اللَّهِ، مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللَّهِ فَهْوَ بَاطِلٌ، وَإِنِ اشْتَرَطَ مِائَةَ شَرْطٍ، شَرْطُ اللَّهِ أَحَقُّ وَأَوْثَقُ ”.

#2 Quran: the only thing left by the prophet
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).

#3 Only Preserved Divine Revelation was Quran
Narrated Ash-Shubi: I heard Abu Juhaifa saying, “I asked Ali ‘ Is there anything that is not in the Quran?’ {Once he said, what is not with the people?} Ali replied, ‘By Him Who made the grain split (germinate) and created the soul, we have nothing except what is in the Qur’an. The only understanding He gives man is in His book Bo ok and w hat is written in this paper.’ I asked, ‘What is written in this paper?’ He replied, ‘Al-Aql (the regulation of Diya), about the ransom of captives, and the Judgment that a Muslim should not be killed in Qisas (equality in punishment) for killing a disbeliever.”

#4 What was written on that paper?
Narrated `Ali: We have nothing except the Book of Allah and this written paper from the Prophet (wherein is written:)
“The Sacred City, what is between ‘Aer and such and such, whoever he narrates therein a Hadith (innovation) or sheltered a propagator of Hadith (innovator), then upon him is the curse of God, the angels, and all the people. Not He will accept from him an excuse and not a ransom. [And he said] The responsibility of the Muslim (Submitter) is one. Then whoever he violated (his responsibility with) a Muslim (Submitter), then upon him is the curse of God, the angels, and all the people. Not He will accept from him an excuse and not a ransom. And whoever he turned away a people without the permission of his master, then upon him is the curse of God, the angels, and all the people. Not He will accept from him an excuse and not a ransom.”

#5 Quran is sufficient
When the prophet offered to write something for his companions before he died that he stated would cause them not to go astray, the response was that they already had the Quran and the Quran was sufficient for them.
Narrated ‘Ubaidullah bin `Abdullah: Ibn `Abbas 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 `Umar 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 `Abbas came out saying, “It was most unfortunate (a great disaster) that Allah’s Messenger (ﷺ) was prevented from writing that statement for them because of their disagreement and noise.
حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَمَّا اشْتَدَّ بِالنَّبِيِّ صلى الله عليه وسلم وَجَعُهُ قَالَ ” ائْتُونِي بِكِتَابٍ أَكْتُبُ لَكُمْ كِتَابًا لاَ تَضِلُّوا بَعْدَهُ ”. قَالَ عُمَرُ إِنَّ النَّبِيَّ صلى الله عليه وسلم 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 صلى الله عليه وسلم وَبَيْنَ كِتَابِهِ.

#6 The Best Hadith
Narrated `Abdullah: The best talk (Hadith) is Allah’s Book ‘Qur’an, and the best guidance is the guidance of Muhammad, and the worst commands are the innovators (hadith) of it; and whatever you have been promised will surely come to pass, and you cannot escape (it).
Sahih al-Bukhari 7277 https://sunnah.com/bukhari:7277
[Quran 39:23] GOD has revealed herein the best Hadith; a book that is consistent, and points out both ways (to Heaven and Hell). The skins of those who reverence their Lord cringe therefrom, then their skins and their hearts soften up for GOD’s message. Such is GOD’s guidance; He bestows it upon whomever He wills. As for those sent astray by GOD, nothing can guide them.
Abu Sa`id Al-Khudri added that the Prophet (ﷺ) further said: “I will say those people are from me. It will be said, ‘You do not know what changes and new things they did after you.’ Then I will say, ‘Far removed (from mercy), far removed (from mercy), those who changed (the religion) after me!”

Conclusion
25:27 The day will come when the transgressor will bite his hands (in anguish) and say, “Alas, I wish I had followed the path with the messenger.
25:28 “Alas, woe to me, I wish I did not take that person as a friend.
25:29 “He has led me away from the message after it came to me. Indeed, the devil lets down his human victims.”
25:30 The messenger* said, “My Lord, my people have deserted this Quran.”
