Hazrat Mirza Ghulam Ahmad claimed to be the Mujaddid of the fourteenth century Hijra. He claimed to fulfil in his person the prophecies of Islam relating to the coming of the Messiah among the Muslims, the Promised Messiah. The Holy Quran promises that God will raise, among the Muslims, Khalifas (deputies or successors) to the Holy Prophet Muhammad:

By "those before them" are meant the Israelites. The Holy Prophet Muhammad said in explanation:

The khalifas of the Holy Prophet include not only his successors who possessed worldly rule, such as Hazrat Abu Bakr and Umar, but also his spiritual successors who came to revive the true teachings of Islam in every age. The spiritual khalifas are also mentioned in another hadith of the Holy Prophet in the following words:

Such a person is known as a mujaddid (reviver or reformer). In accordance with all these prophecies, several renowned figures in the history of Islam have been recognised by the Muslims generally as being mujaddids of their centuries and spiritual khalifas of the Holy Prophet. Among them were: Umar ibn Abdul Aziz (1st century Hijra), Imam Ghazali (5th century), and Shah Wali-ullah of India (12th century). In fact, Shaikh Ahmad of Sirhind (India), the mujaddid of the 11th century Hijra, is commonly known as Mujaddid Alif Sani (the mujaddid appearing at the start of the second millennium).

In accordance with this tradition, Hazrat Mirza Ghulam Ahmad claimed to be the Mujaddid of the 14th century Hijra (1883-1979) and a spiritual khalifa of the Holy Prophet Muhammad. By believing him to be Mujaddid, we are not adding any new belief to Islam, but only following Islamic practice as recognised by the Ahl as-Sunna.
