Answer by taking a quote from the following article:

Mirza Basheer-ud-Din Mahmood was born to Ghulam Ahmad and Nusrat Jahan Begum on 12 January 1889 in Qadian, the same year in which Ghulam Ahmad established the Ahmadiyya Movement by accepting allegiance from his disciples. Due to chronic illness Mahmood Ahmad was unable to attend to secondary education. During his youth, he remained an active member in the service of the Movement by founding a journal entitled Tash'heezul Az'haan and accompanied his father on many of his journeys. On 26 May 1908, Ghulam Ahmad died in Lahore when Mahmood Ahmad was 19 years old.

In 1934 Mahmood Ahmad claimed to have been divinely inspired to launch a twofold scheme for the establishment of foreign missions and the moral upbringing of Ahmadis. This initiative called upon members to volunteer themselves for missionary work, and to donate money towards a special fund for propagation in foreign countries during the course of which 46 foreign missions were established. The Tehrik-e-Jedid and Waqf-e-Jedid or the 'new scheme' and the 'new dedication' respectively, initially seen as a spiritual battle against the oppressors of the Ahmadis, placed before them a number of demands and restriction such as leading simple lives, restrictions against eating, clothing etc.; a temporary ban on all forms of luxury and entertainment. It called upon the members of the Community to dedicate their time and money for the sake of their faith. In time the scheme produced a vast amount of literature in defence of Islam in general and the Ahmadiyya beliefs in particular. The funds were also spent on the training and dispatching of Ahmadiyya missionaries outside the Indian sub-continent and their sustenance. As part of this Mahmood Ahmad appointed 5 men to survey the Punjab in order to find out the best way of disseminating the Ahmadiyya teachings. For the first time an organised method of training members of the community for becoming missionaries was established. Addressing the Ahrari opposition Mahmood said: In order to expand the propagation of Islam I have urged the youth to come forward and dedicate their lives for the service of religion. Hundreds of young people have already responded to my call. These graduates are given only 15 rupees a month as an allowance. This is a small allowance that barely caters for their basic needs. Yet living on that paltry sum they travel to other countries and propagate the message of Islam. I invited the members of the Community to come forward and make financial contributions, at the same time I said that the time had not yet come for greater sacrifices. I appealed for only 27,000 rupees whereas the community promised 108,000 rupees out of which more than 82,000 rupees have already been received. As well as administering proselytisation the scheme also carried the responsibility of a more internal aspect and called upon members of the Community to dedicate their lives for the teaching and moral upbringing of Ahmadis themselves in rural places within India. Later, permanent offices of this scheme were established. The scheme was to grow into international proportions during the leadership of later Caliphs of the Ahmadiyya Muslim Community.

Was the New Scheme part of Islam?
In order to expand the propagation of Islam I have urged the youth to come forward and dedicate their lives for the service of religion.
