The role of delegations of the Prophet's time in publishing the Prophetic Sunnah and Hadith

The sayings, practices and taghrir of the Prophet (pbuh) have been spread in the early Islamic society under the influence of various factors and have been transferred to later periods. In addition to the assertions and teachings of the Prophet, another factor was the arrival of groups of new Muslims or seekers of truth to the presence of the Prophet, who were called "Wufud". The actions of "Wufud" include announcing the acceptance of the Prophet's mission, request the prophet's representative to accompany them to teach them the rules of Islam, and bilateral agreements in the field of war and peace. On the other hand, the Prophet's effort was to teach the principles of belief, Quran and the rules of religion, determine financial duties and sending letters and sending agent. By examining the books of history, Prophetic biography and schools related to the beginning of Islam, the most important issues exchanged and actions taken during the delegation's meeting with the Prophet can be read. The most important results of these journeys in the spread of Islam and the publication Sunnah, the following are worth mentioning: the teaching of monotheism and emphasis on ruin of the manifestations of polytheism, laying the foundations for the expansion of the territory of Islam, teaching the Qur'an and publishing its teachings, teaching prayer, explaining the financial rules of Islam, especially zakat. Knowing the methods and content of the Prophet's programs in this field can lead to more success in the present era.
