Proof That the Quran Is Complete and That the Hadith Books Are Not Needed

Following is proof that the Quran alone is sufficient and complete for the purposes of Islamic guidance and law. Consequently, the hadith books are not needed to supplement or clarify the Quran.

The Quran is complete

Fortunately, we don’t need to guess whether verse 31:27 suggests that the Quran is complete. God admits in verses 6:115 and 6:38 that the Quran is complete. Also, common sense says that God is perfect. Therefore, why would God send down an incomplete Quran? Was God too busy that He couldn’t finish the Quran? Obviously not. Did God say in the Quran that because the Quran is incomplete, we have to figure out the missing parts from Prophet Muhammad’s sayings (hadith)? Obviously not.

و َتَمَّتْ كَلِمَتُ رَبِّكَ صِدْقًا وَعَدْلًا ۚ لَّا مُبَدِّلَ لِكَلِمَاتِهِ ۚ وَهُوَ السَّمِيعُ الْعَلِيمُ

And the word of your Lord has been fulfilled in truth and in justice. None can alter His words, and He is the Hearing, the Knowing. (6:115)

وَمَا مِن دَابَّةٍ فِي الْأَرْضِ وَلَا طَائِرٍ يَطِيرُ بِجَنَاحَيْهِ إِلَّا أُمَمٌ أَمْثَالُكُم ۚ مَّا فَرَّطْنَا فِي الْكِتَابِ مِن شَيْءٍ ۚ ثُمَّ إِلَىٰ رَبِّهِمْ يُحْشَرُونَ

And there is no creature on [or within] the earth or bird that flies with its wings except [that they are] communities like you. We have not neglected in the Register a thing. Then unto their Lord they will be gathered. (6:38)

The Quran is fully detailed (fussilat) of all things

Not only is the Quran complete, but it’s also detailed.

أَفَغَيْرَ اللَّهِ أَبْتَغِي حَكَمًا وَهُوَ الَّذِي أَنزَلَ إِلَيْكُمُ الْكِتَابَ مُفَصَّلًا

[Say], “Then is it other than Allah I should seek as judge while it is He who has revealed to you the Book explained in detail?” (6:114)

لَقَدْ كَانَ فِي قَصَصِهِمْ عِبْرَةٌ لِّأُولِي الْأَلْبَابِ ۗ مَا كَانَ حَدِيثًا يُفْتَرَىٰ وَلَٰكِن تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ كُلِّ شَيْءٍ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ

There was certainly in their stories a lesson for those of understanding. Never was the Qur’an a narration invented, but a confirmation of what was before it and a detailed explanation of all things and guidance and mercy for a people who believe. (12:111)

كِتَابٌ فُصِّلَتْ آيَاتُهُ قُرْآنًا عَرَبِيًّا لِّقَوْمٍ يَعْلَمُونَ

A Book whose verses have been detailed, an Arabic Qur’an for a people who know, (41:3)

الر ۚ كِتَابٌ أُحْكِمَتْ آيَاتُهُ ثُمَّ فُصِّلَتْ مِن لَّدُنْ حَكِيمٍ خَبِيرٍ

Alif, Lam, Ra. [This is] a Book whose verses are perfected and then presented in detail from [one who is] Wise and Acquainted. (11:1)

The Quran provides its own explanation (ahsan tafsir)

Not only is the Quran complete and detailed, but it also provides its own explanation (tafsir) of things and it is the best explanation (tafsir).

وَلَا يَأْتُونَكَ بِمَثَلٍ إِلَّا جِئْنَاكَ بِالْحَقِّ وَأَحْسَنَ تَفْسِيرًا

And they do not come to you with an argument except that We bring you the truth and the best explanation. (25:33)

The Quran is sufficient as a book of guidance.

No other book, e.g. the hadith, is necessary to complement the Quran as God indicates that the Quran alone is sufficient.

أَوَلَمْ يَكْفِهِمْ أَنَّا أَنزَلْنَا عَلَيْكَ الْكِتَابَ يُتْلَىٰ عَلَيْهِمْ ۚ إِنَّ فِي ذَٰلِكَ لَرَحْمَةً وَذِكْرَىٰ لِقَوْمٍ يُؤْمِنُونَ

And is it not sufficient for them that We revealed to you the Book which is recited to them? Indeed in that is a mercy and reminder for a people who believe. (29:51)

The fact that the Quran is sufficient all by itself is further indicated in verses 17:45-46. Note the emphasis of the Quran being sufficient on its own with the use of the word “alone”.

وَإِذَا قَرَأْتَ الْقُرْآنَ جَعَلْنَا بَيْنَكَ وَبَيْنَ الَّذِينَ لَا يُؤْمِنُونَ بِالْآخِرَةِ حِجَابًا مَّسْتُورًا

And when you recite the Qur’an, We put between you and those who do not believe in the Hereafter a concealed partition. (17:45)

وَجَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِي آذَانِهِمْ وَقْرًا ۚ وَإِذَا ذَكَرْتَ رَبَّكَ فِي الْقُرْآنِ وَحْدَهُ وَلَّوْا عَلَىٰ أَدْبَارِهِمْ نُفُورًا

And We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And when you mention your Lord in the Qur’an alone, they turn back in aversion. (17:46)

God never runs out of words

Many people seem to think that the Quran is incomplete and therefore, believe that Prophet Muhammad’s sayings (hadith) complete the Quran. According to verse 31:27, God never runs out of words. Therefore, God could have written more words in the Quran to explain things to people. But since God didn’t write more than what’s in the Quran, He must have considered the Quran complete.

وَلَوْ أَنَّمَا فِي الْأَرْضِ مِن شَجَرَةٍ أَقْلَامٌ وَالْبَحْرُ يَمُدُّهُ مِن بَعْدِهِ سَبْعَةُ أَبْحُرٍ مَّا نَفِدَتْ كَلِمَاتُ اللَّهِ ۗ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ

And if whatever trees upon the earth were pens and the sea [was ink], replenished thereafter by seven [more] seas, the words of Allah would not be exhausted. Indeed, Allah is Exalted in Might and Wise. (31:27)

The best hadith (statement) is God’s statement (the Quran)

In verse 39:23, God says that the best saying / statement (hadith) is God’s hadith. So why would anyone want to follow some other hadith, e.g. via Bukhari, Muslim, Tirmidzhi, etc?

اللَّهُ نَزَّلَ أَحْسَنَ الْحَدِيثِ كِتَابًا مُّتَشَابِهًا مَّثَانِيَ تَقْشَعِرُّ مِنْهُ

Allah has sent down the best statement: a consistent Book wherein is reiteration. …(39:23)
