There is a subtle difference between 'hawaari' & 'sahabi'.
Disciple are blind followers. 'As-haab' (Companions) or 'Walladheena-Ma'ahu' (those with him) are very democratic.
RABBANIYYEEN (Devotees of God)
3:79 Never would a human being whom God has blessed with the Scripture, wisdom and even Prophetic office, thereafter say to people, “Be servants of me instead of God.” Rather, he would say, “Become true devotees of the Lord according to the Scripture you teach and explain.”
Sahabi is a two way street. Look at 'your companion', the exalted prophet.
34:46 Say, "I ask you to do just one thing: For the sake of God! Stand up in pairs and singly, and then think. There is no madness in your companion. He is only a warner to you in the face of a terrible doom."
