The issue of Shia-Sunni conflict has had different political, social, cultural and scientific dimensions during the past fourteen centuries. To the extent that the scientific dimensions of this difference have been highlighted, not only the social and cultural intensity of the difference has been reduced, but the deep knowledge of the parties has become more apparent, and on the other hand, as much as the scientific dimensions of the differences between the parties have been reduced, the intensity of the social, cultural and political differences has increased. One of the brilliant periods in this field is the establishment of Dar al-Taqrib in the 20th century, which caused the scholars of Islamic religions to gather together and maximum compliments took place between the scholars. One of the important results of this period was the historical fatwa of Sheikh Mahmoud Shaltut in recognizing Jafari jurisprudence along with the four official Sunni jurisprudences, and the launch of Risala al-Islam magazine. Very valuable articles were published in this magazine. One of these articles was Allameh Semnani's article under the title of "Practice Method of Approximation". In this article, citing the biography of Ahl al-Bayt, Allameh Semnani shows that neither the belief in the infallibility of the Ahl al-Bayt contradicts the caliphate of the just and righteous caliphs, nor does the belief in the caliphate of the righteous caliphs’ conflict with the infallibility and infallibility of the Ahl al-Bayt. The adoption of such a scholarly and unificationist approach shows the depth of knowledge and foresight of the insightful scholars, which has always been forgotten due to the predominance of the extremist and divisive factions of the parties. It is hoped that the translation of this valuable article will be considered a step, however small, in the path of recognition and convergence of Shia and Sunni.
