On 20th February 1886, Allah revealed to Hadhrat Mirza Ghulam Ahmad (as), a glad tiding pertaining to the arrival of a righteous progeny who will prove to be the light of Allah in the fullness of time.
“I confer upon thee a Sign of My mercy according to thy supplications. I have heard thy entreaties and have honoured thy prayers with My acceptance through My mercy and have blessed this thy journey.
A sign of power, mercy, nearness to Me is bestowed on thee. A Sign of grace and beneficence is awarded to thee and thou art granted the key of success and victory. Peace on thee, O victorious one. Thus does God speak so that those who desire life may be rescued from the grip of death and those who are buried in the graves may emerge therefrom and so that the superiority of Islam and the dignity of God's word may become manifest unto the people and so that the truth may arrive with all its blessings and falsehood may depart with all its ills, and so that people may understand that I am the Lord of Power, I do whatever I will, and so that they may believe that I am with thee, and so that those who do not believe in God and deny and reject His religion and His Book and His Holy Messenger Muhammad, the chosen one (on whom be peace) may be confronted with a clear sign and the way of the guilty ones may become manifest.
