The Book of marriage – part three – Explanation of Bulugh al-Maraam

'Ali Ibn Abū Ṭālib is the nephew of the Messenger (May Allah exalt his position and grant him peace). Fatima is the daughter of the Messenger (May Allah exalt his position and grant him peace), the most prestigious lady in Paradise (May Allah be pleased with her) as stated by the Prophet (May Allah exalt his position and grant him peace) . In addition, the Prophet (may Allaah raise his position and grant him peace) said about 'Ali (may Allaah be pleased with him):

"You are in the same position with regard to me as Aaron (Hārūn) with regard to Moses, but with (this explicit difference) that there is no prophet after me."

He said this when he delegated to him the responsibility of [Madīnah] when Muslims were away from the conquest of Tabūk. So he said: O Messenger of Allah! You leave me with wives and children? The Prophet (may Allah exalt his position and grant him peace) said the above narration to warm his heart. It is also because Aaron (Hārūn) took the place of Mūsā among his people, as he said:

"Replace me among my people." [Sūrah 'Al-Aʿrāf (7):142]

The previous ʾĀyāt explains the following statement: "You are in the same position with regard to me as Aaron (Hārūn) with regard to Mūsā."

However, when the Prophet (may Allah exalt his position and grant him peace) feared that someone would misuse this word and claim that Ali is a prophet like Harūn, he said:

"but with (this explicit difference) that there is no prophet after me." This statement emphasizes the immense protection that the Prophet (may Allah exalt his position and grant peace) devoted to the prestige of the Message [of Islam]. He is also concerned about the importance of Tawhid (Islamic Monotheism). Certainly, according to the Qur'an and the Sunnah, it is well known that he is the last of the Prophets and that there is no Prophet after him.
