The revelation is as follows:You are to Me like My Unity and Uniqueness.
Ahmad(as) has himself explained this beautifully. He states:
I understand this to mean that when someone is appointed to uphold the Unity of God and appears at a time when people are looking down upon and disrespecting the Unity of God, the appointed person develops such a zeal for Unity of God that he disregards all his aims and objectives and devotes himself exclusively to this task, thus becoming Unity personified. All his movements and words are charged with the spirit of Unity. People in the world have turned their lowly objects into idols. Until Allah the Almighty Himself charges someone with this zeal, it cannot be acquired. Just as some people are so restless about their children and other objectives that they sometimes commit suicide; in the same way, the appointed one is restless to establish Unity. He desires that the will of God, and His Unity, Greatness and Grandeur should prevail.”( [al-Badr, vol. 2, no. 12, dated April 10, 1903, p. 91, column 2] )
