"Your companion [Muhammad] has not strayed, nor has he erred,"(53:2)
"Nor does he speak from [his own] inclination."(53:3)
"It is not but a revelation revealed,"(53:4)
"Taught to him by one intense in strength -"(53:5)
"One of soundness. And he rose to [his] true form"(53:6)
The Companions were the ones who narrated the hadith,and not only that The Quran is clear in its wording,The Companion has not erred or strayed,so therefore the Hadith must be true,as they are from the Companions.
And his revelation was specifically revealed to the Prophet SAW,and it never says the revelation is in the Quran. infact it says a Sahabi was taught this revelations,in which he made it into a narration.
So therefore this can only be the hadith,nothing else.
