Under his leadership, there was further expansion of missionary work started by his predecessor the second caliph, particularly in Africa and Europe. In 1974, he represented the Ahmadiyya Community in the National Assembly of Pakistan in an eleven-day inquisition. 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. the "Nusrat Jehan Scheme", a scheme dedicated to serving parts of Africa by running numerous medical clinics and schools was one of the many outcomes of his 1970 tour of West Africa, the first visit to the continent made by an Ahmadi caliph. In 1980, Nasir Ahmad traveled to Spain, where he laid the foundation stone of the Basharat Mosque in Pedro Abad. The mosque was inaugurated posthumously in 1982 and was the first purpose-built mosque in Spain since the Reconquista and the Fall of Granada in 1492.
