One of the historical accusations that have been raised against Shia since the first centuries is the "Khan Al-Amin" issue. Some historical and sectarian sources have said that the Shiites, or at least a group of them called "Ghorabiyyah", believe that Gabriel betrayed the Commander of the Faithful (AS) and instead of conveying the revelation to him, he conveyed it to the Holy Prophet (PBUH). . The inconsistency of this belief with Shia jurisprudence and beliefs and the lack of mention of such belief or sect in the historical and sectarian sources of Shias and the ancient sources of Sunni sectarianism testify to the falsity of this accusation. This research seeks to achieve the process of attributing this belief to Shiites. For this purpose, after examining the history of the use of this accusation, the currents and people who played a role in the formation and spread of this accusation have been scrutinized, and the main source of this accusation has been introduced, the Umayyad Umayyads and some court scholars such as Shaabi (104 AH).
