Mirza Nasir Ahmad (مرزا ناصر احمد; 16 November 1909 – 9 June 1982) was the third Caliph (Arabic: خليفة المسيح الثالث, romanized: khalīfatul masīh al-Thālith) of the Ahmadiyya Muslim Community from Pakistan.

Despite his efforts, the National Assembly declared Ahmadis to be non-Muslims and he led the Community through this period of increased hostility and government repression.

In 1980, Nasir Ahmad traveled to Spain, where he laid the foundation stone of the Basharat Mosque in Pedro Abad and announced "Love for All, Hatred for None" as the community's motto.

The writings of Ghulam Ahmad, which had hitherto been published as individual books, pamphlets or articles were compiled in the twenty-three volume corpus known as Rūhānī Khazā᾽in (Spiritual Treasures).

[12] Before returning to India he visited Egypt for three months from July to November 1938 in order to improve his Arabic and to meet up with his brother Mirza Mubarik Ahmad to analyse the progress of the Community in Cairo.

Mirza Nasir Ahmad was elected as Khalifatul Masih III on 9 November 1965, shortly after Isha prayer at Mubarak Mosque in Rabwah, Pakistan.

In 1971, the Khilafat Library in Rabwah was inaugurated, which today houses over 100,000 books, rare manuscripts, a children's section and science displays.

During his visit, he attended numerous receptions held in his honour and inspected the educational, social as well as spiritual services rendered by the Ahmadiyya Muslim Community of various African countries.

Under this scheme, Ahmadi doctors and teachers are serving in various parts of Africa by running numerous medical clinics and secondary schools.

In 1978, Mirza Nasir Ahmad traveled to London where the conference of Jesus’ Deliverance from the cross was held at the Commonwealth Institute in Kensington.

The Christian Church gave a statement dismissing the Ahmadiyya as not representing the teachings of Islam and refused to be drawn into the debate that had been re-opened by the discovery of the Shroud of Turin and now this conference.

He dealt with the subject of Jesus’ survival from death upon the cross, his travel to the east, the Unity of God, and expounded the status of Muhammad.

This was published in the form of the Malfoozat, which include his discourses, speeches, question and answer sessions, sermons and casual sayings.

In 1980, Mirza Nasir Ahmad traveled to Spain, where he laid the foundation stone of the Basharat Mosque in Pedro Abad.

In his lifetime, especially during the caliphate, Nasir Ahmad gave many lectures or sermons, wrote discoursers and treaties, but most of them weren't written as a book.
