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 ibn Abi Talib to him with the standing of Aaron to Moses, with the exception that Ali is not a prophet. In Shia Islam, this hadith is invoked to prove Ali's usurped right to succeed Muhammad.
