It is not (possible) for any human being to whom Allah has given the Book and Al-Hukma (the knowledge and understanding of the laws of religion, etc.) and Prophethood to say to the people: "Be my worshippers rather than Allah's." On the contrary (he would say): "Be you Rabbaniyun (learned men of religion who practise what they know and also preach others), because you are teaching the Book, and you are studying it."
