The narration of the coronation of Ali bin Abi Talib at Al-Ghadir is an addition that is less known. Crowns were not common in the Arabian heartlands, and therefore, turbans were seen in some cases as crowns. The hadith of the coronation is one in which the Prophet (peace be upon him) allegedly places his turban, which was named “Al-Sahab” (the Cloud) upon the head of Ali. He does this as a form of symbolism that Ali is his successor.
Unlike previous article of the congratulating of Ali, Al-Amini quotes a relatively small number of sources. Again, much of what he quotes traces back to a source or two.
The narration comes through the path of Abdullah bin Busr from Abdul Rahman bin Adi Al-Bahrani from his brother Abdul A’ala from the Prophet (peace be upon him) with a disconnected chain.
Al-Bayhaqi narrates it from the path of Al-Ash’ath bin Sa’eed bin from Abdullah bin Busr from Abi Rashid Al-Hubrani from Ali, but he points out that this chain is incorrect. Refer to Al-Sunan Al-Kubra #19736. The narration is also narrated in Ma’rifat Al-Sahaba by Abi Nu’aym.
In either case, Abdullah bin Busr Al-Saksaki is the common link in the report and he is weakened by Yahya bin Sa’eed, Al-Tirmithi, Al-Nasa’ee, Abu Hatim, Al-Daraqutni, and Abu Dawud.
Refer to his biography in Tahtheeb Al-Tahtheeb.
Another chain that is used for this report is a lengthy one by the author of Fara’id Al-Simtain 1/76, however, it comes through the path of Abu Tahir Ahmad bin Eisa bin Abdullah, who was declared to be a liar by Al-Daraqutni in his Dhu’afa (289).
In conclusion, there are no authentic traditions for this alleged coronation.
