Islam is also in the Hadiths. How else would you know the 5 pillars of Islam, if not for the Hadiths?
I am willing to accept your argument, provided any imam, learned in Islam, does! The fact is, and you know very well, Muslim scholars accept the Sahih Hadiths as authentic, and disbelieving them is a sign of Kufr! So you will never dare to take your wonderful arguments and argue with your own religious scholars who believe the Hadiths, and use them to brainwash young Muslim minds, teaching them that the Prophet' behaviour was the model that they should try to copy!
