MGA contradicted himself all the time. From as early as 1880-1884 era. In this era, he told the world that he was only “LIKE-Esa” and even though his revelations indicated something else, he was only “LIKE-Esa” or “maseel e Maseeh”. However, 7 years later, he totally contradicted himself and claimed to actually be “Esa (as)”, which is blasphemous.
The Quote from 1907
“The conferment of titles is the pleasure and the work of the Lord God. I have no share in it. As for the question why I have written like this? Why has this contradiction crept in? So, please, listen and understand with care. This contradiction is of the same kind as in Barahin-i-Ahmadiyya I wrote, at one time, that the Messiah, son of Mary, could descend from the heavens. Later on, however, I put forth that I, myself, am the Messiah expected to come in the later times. The basis of the contradiction in that case was the same. Although, in Barahin-i-Ahmadiyya itself, the Lord God called me Isa and also said to me that the tiding of my advent had been given earlier by God and His Apostle. Since, however, a portion of the Muslims happened to have become firm on the belief, and I myself believed the same, that Hazrat Isa would come down from the heavens, I endeavoured to take the Wahyi at the apparent level; in fact, I watered it down in interpretation, and clung to the former view I had shared with the rest of the Muslims; and this was the view I did my best to propagate in Barahin-i-Ahmadiyya. Later on, however, Revelations came down on me, like the rain from heaven, to the effect that I myself was the Promised Messiah, so eagerly expected to appear, with hundreds of wonderful Signs and the earth, as well as the heavens took their stand in support of my position; and brilliant manifestations forced me to perceive that I, myself, was the Masih expected to appear in the later times. Otherwise, my belief on these points was the same as I had stated in Barahin-i- Ahmadiyya…
Similarly, to begin with this was my belief that in no way was I comparable in quality with reference to Jesus son of Mary. He was a Prophet, great among those chosen by the Lord. Even when something occurred, which seemed to establish my superiority over him, always I took it to imply some limited and partial preference. Later on, however, the Wahyi sent down on me by the Lord, like pouring rain, it did not allow me to remain clinging to this belief; and I found the title of Nabi clearly conferred on me, in a manner that I was a Nabi from one angle, an Ummati from another… Anyway, the long and short of it all is this that there is no contradiction in what I say, I but follow the Wahyi, from the Lord. Just as long as this awareness did not come to me, I continued to say what I had said at the outset. But when I was given this awareness, I began to say different from what I had said before. I am no more than a human being: I do not claim to be the Knower of the Unseen.” (Haqiqatul Wahyi, page 148-150)
MGA surely claimed prophethood sometime in his career, more specifically from the summer of 1900 to Nov 1901, he made the claim. He claimed to be the only person in the entire Ummah who was given the name Nabi, etc etc etc.
