**6.3 Brotherhood (offspring)**

Brotherhood in Islam is like a human being with a perfect body. If one limb is sick, then the whole body will be sick. Therefore, there needs to be a bond between individuals with one another in a team. Cooperation, consideration, solidarity may strengthen the bond of brotherhood. There must be a high determination in each member of the organization to express the meaning of commitment in the organization. An understanding of religious life, with an emphasis on morality and fighting for social justice, is the main spice for developing a competitive socio-economy society [22].

In the view of Islam, the development will be born when human needs, natural and social resources can be preserved from the elements of lust that only pursue the pleasures of life to boast of wealth and luxury. The spirit of brotherhood built in a society will be able to guard against greed. Members of the community can live a life that prioritizes a spirit of cooperation, consideration, and even solidarity with other less fortunate members of the community. Charity and knowledge become an added value to human life that binds progress and the pursuit of happiness as part of the human responsibility of living on earth. Community life on the principle of brotherhood will actually be able to develop a society that lives in harmony [23].

Rabbani leadership designed the framework of social justice to bring harmonies life through his moral teachings [14]. The effort led to restructure the resources to settle down the problem faced during the administration period. The only reliable way to do by launching the concept of Islamic brotherhood so that they started to think of every follower as their brother regardless of the color, caste, and clan. This notable policy showed Rabbani leader is a successful leader, undoubtedly. The notion of Islamic brotherhood is an optimal solution for this problem that unity is the foundation for the harmonious life of society. This work provided proof that binding the humanitarian relationship between multi followers' social backgrounds may grow up a positive way as a progressive society.

Rabbani leaders do the pervasiveness of coalitions or set alliances with any agencies as mechanisms of upgrading the organization's influence, by convincing peers, subordinates, superiors, and outsiders to join forces to pursue their common interests. This approach shows a move that officially marked the start of the development collaboration between the followers and outsider agencies.
