From where does a Muslim take his creed and faith

The Muslim takes his creed and faith from the Book of Allah (the Qur’an) and the authentic Sunnah of His Prophet Sallah Allahu 'Alayhe wa Sallam (peace be upon him), who does not speak of his own desire, rather (as Allah says):
((It is only revelation revealed.)) (53:4)

These two sources should be understood according to the understanding of the companions (Sahaabah), and the righteous predecessors
