Hawzah News Agency- the Holy Prophet (peace and blessings of Allah be upon him) delivered the Ghadir sermon, which was dedicated to prove Imam Ali's (peace be upon him) governorship, in a public conference attended by all Muslims.
This shows that the Holy Prophet (peace and blessings of Allah be upon him) wanted to convey the special political guardianship of the Imam (peace be upon him) to the general society because this type of guardianship is a matter that is aimed at the public. It was established between the Imam (peace be upon him) and every Muslim, there was no need to introduce him to the general Muslim community, because this guardianship already existed.
