Abu Zayd̛s approach in Sunnah(tradition) and it̛s authenticity(hujjiyah)

Using two principles; distinction between religion and religious knowledge, and historical theory, Abu Zeyd considered sunnah by hermenutic approach (theory).
He believed the expression of sunnah and giving it wide spreading authenticity, as religious knowledge which is made (up) by scholars after the Prophet (pbuh) period. Thus for him, there is no reason to accept it, so it was criticized by.
Depending on historical theory, he expressed the Prophet (pbuh) as human who is limited in temporal and local circumstances in his life. So his sunnah was historical question which should not been followed. In his viewpoint, the sunnah of the Prophet was not inspirational but accompanied with human faults, and it even was not followed in Prophecy period. For the sake of this, it was not codified and gathered.
Abu Zeyd viewpoint has serious problems because of using deficient basis in this subject and also applying by entering style and not scientific base, also neglecting documents which appose and reverse his theory. So his approach about sunnah and its validity is not acceptable.
