Barahin-e-Ahmadiyya contains the following prophecy:
I shall demonstrate My light and shall raise you with a demonstration of My power. A Warner came unto the world, but the world accepted him not; yet God shall accept him and demonstrate his truthfulness with mighty assaults.
As many as twenty-five years have passed since the announcement of this prophecy. It belongs to a time when I was nobody. The essence of this prophecy is that on account of bitter opposition—both internal and external—there would be no visible prospects for this Movement to be established, but God, with His lustrous Signs, would draw the world towards it and would display mighty assaults to attest to my truth. Thus, the plague is one of these ‘assaults’ which was foretold long ago.
Also among those assaults are the earthquakes that are shaking the world. No one knows what other assaults will occur! As had been foretold in this prophecy, there is not the least doubt that God has established this Jama‘at through the sheer manifestation of His power; otherwise, in the face of such nationwide opposition, it was simply inconceivable that hundreds of thousands would accept me in such a short time. The opponents tried hard, but remained utterly helpless in opposition to the will of God.
