Based on the analysis of the studied researches, five important steps were taken in designing the strategy of approximating Islamic religions; In the first step, the goals were determined and in the second step, policies were made; In the third step, the factors, conditions and obstacles were considered; In the fourth step, the solutions were considered, and in the fifth step, the strategies proposed in the studied studies were examined and analyzed; Based on this process, the goal of approximation was to reach a unified nation and a new Islamic civilization based on principles such as the principle of paying attention to the foundations of approximation, the principle of de-escalation, and the principle of supporting the oppressed and anti-arrogance; If it is necessary to pay attention to conditions such as self-righteousness, goodwill, acceptance of each other and obstacles such as excommunication of each other, pseudo-casting, superficiality, and dissension of enemies.
