Salam,
It's clear that Al-Murtada isn't comfortable with the hadith as well and tries to de-antropomorphosize it while there are sunni scholars who love to emphasize the claim that man is created in God's image. Must be jewish ancestry or influence or something.
The Judaization of Islam started with the interrest of Umar for the Taurat and consulting the converted jew Ka'ab al-Ahbar. This consulting of him continued during the caliphate of Uthman as well as Muawiya the governor who also consulted him often,
This Ka'ab told Umar to put the altar of the Dome of the Rock towards the sakhra (Jewish Qiblah).
I can't say that there is no Israiiyat influence in Shi'a ahaadith for there is but there are elements of Israiliyat incorporated in the creed of Sunni Islam and it should be located and erased.
