Brother, its clear to me that u are just trying to have a religious debate here, put this foolishness to rest, but i'll entertain you for one more and that's it, islam is both the quraan and authentic sunna, which teaches us the way it is applied, hence why it doesnt tell you how to pray in the quraan but in the sunna, quraanists who take everything literal, without the wisdom and actual interpretation are dangerous, since they can interpret any verse, the way THEY see it, not the way it actually is, u could have used a simpler example for the word dharab, in chapter 34 verse 4, a quraaniost can read it and say yes im gonna cut my wife's neck, ( in referrence to surah muhammed verse 4 ) or just beat her close to death, but yeah, quraanists cannot be called muslims since they dont believe in the sunna, hence can't even pray
