Hazrat Mirza Masroor Ahmad, Khalifatul-Masih V, may Allah be his Helper, stated:
“[Allah the Almighty] informed the Promised Messiah (peace be upon him): ‘Your Movement will not remain limited to you alone. The mission for which you have been raised will not be confined to your lifetime; rather, you will be granted a son who will be unique in his high resolve, who will be like you in his passion to spread Islam throughout the world, whose heart will burn with the desire to plant the flag of Muhammad, the Messenger of Allah (peace and blessings of Allah be upon him), across the earth.’ And this mission would not remain limited to that son alone; rather, Allah the Almighty also promised the Promised Messiah (peace be upon him) that the Second Manifestation would continue until the Day of Judgement, taking this mission forward to the corners of the earth. This Second Manifestation—established in the form of Khilafat—would be granted such devoted helpers, Sultan-e-Naseer, who would advance the mission of the true servant of the Holy Prophet (peace and blessings of Allah be upon him).
“Thus, today, the prophecy of Musleh-e-Mau’ud not only stands as a proof of the truth of the Promised Messiah (peace be upon him) but also draws our attention to the qualities of the son concerning whom Allah the Almighty had given glad tidings, and to the passion and determination with which that son opened new pathways for the progress of the Jama’at. He bestowed upon us a beautiful administrative system—one that strengthened the moral training of the Jama’at and established a firm structure to convey the beautiful message of Islam to the corners of the world. Its fruits continue to appear each day with new glory. Every Ahmadi must therefore play his or her part in further strengthening this system.”
