He is also the Merciful, the King, etc.
Yet I remember reading the Companions differing on issues on aqida like, Did the Messenger of Allah, sallahu alayhi wa salam, see Allah or not? Was Iblis a Jinn or an Angel? and there are probably more things in which the companions differed.
And Allah knows best.
