that the Prophet (ﷺ) said to 'Ali, "You are to me, in the position that Harun was to Musa, [except that there is no Prophet after me]."
Hadith Commentary: The Status of 'Ali ibn Abi Talib
This narration from Jami' at-Tirmidhi (Hadith 3731) establishes the profound spiritual and administrative status of 'Ali ibn Abi Talib (may Allah be pleased with him) in relation to the Prophet Muhammad (ﷺ). The comparison to Harun (Aaron) and Musa (Moses) carries multiple layers of meaning that classical scholars have elaborated upon.
The Prophetic Analogy
Just as Harun was the brother, deputy, and supporter of Musa, 'Ali occupied the same relationship to the Prophet Muhammad. This includes being a trusted advisor, a military leader, and a spiritual successor in certain capacities.
The exception clause "except that there is no Prophet after me" clarifies that while 'Ali shared all other qualities of Harun's relationship to Musa, the specific office of prophethood concluded with Muhammad (ﷺ).
Scholarly Interpretation
Imam al-Tirmidhi himself classified this hadith as hasan sahih (good and authentic). Classical commentators like Ibn Hajar al-Asqalani and al-Nawawi emphasized that this establishes 'Ali's right to succession in leadership matters.
The analogy indicates that 'Ali was the most qualified companion to lead the community after the Prophet's passing, though scholars differ on whether this was a specific designation or a general indication of merit.
Historical Context
This statement was made during the Tabuk expedition when the Prophet left 'Ali in charge of Medina. When hypocrites spread rumors that the Prophet was displeased with 'Ali, the Prophet clarified his status with this profound analogy.
The timing demonstrates that this was both a practical appointment and a spiritual declaration of 'Ali's elevated station among the companions.
