Hadith of the position
The Hadith of the position (Arabic: حديث المنزلة, romanized: hadith al-manzila) is a widely-reported saying (hadith), attributed to the Islamic prophet Muhammad, that equates the standing of his cousin and son-in-law Ali to him with the standing of Aaron to Moses, with the exception that there is no prophet after Muhammad.
In Shia Islam, this hadith is cited as evidence for Ali's right to succeed Muhammad. In Sunni Islam, the Hadith of Position is understood as affirming the special status and closeness of Ali to Muhammad, while emphasizing the finality of Muhammad's prophethood.
