Is Hadith needed to explain Quran?

If you ask most Muslims: who explains the Quran? They will claim that the prophet explained the Quran through the Hadith. This is because traditionalists believe that without the Hadith, the Quran is incomprehensible.

Except the Hadith does not explain the Quran. You will not find any Hadith that provides a detailed tafsir of three consecutive verses of the Quran. This is because the Hadith is not a Tafsir of the Quran. This is even spelled out in the Hadith.

Not only does the Hadith not explain the Quran, but it also confuses the Quran people.

Also, there is another problem with this argument which is that it leads to an infinite regress. If we say we need the Hadith to explain the Quran, then we will also need another entity to explain the Hadith, and another entity to explain that, and…The reality is that God informs us that He has given us the hearing, eyesight, and the brain, and we are responsible for using these faculties if we would like to understand.

18:57 Who are more evil than those who are reminded of their Lord’s proofs, then disregard them, without realizing what they are doing. Consequently, we place shields on their hearts to prevent them from understanding it (the Quran), and deafness in their ears. Thus, no matter what you do to guide them, they can never ever be guided.
