Hadith.1817 - It is narrated by al-Mufaddal ibn Umar from Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq عليه السلام), who said:
"Fasting on the Day of Ghadir Khumm is an expiation for sixty years."
As for the report regarding the prayer on the Day of Ghadir Khumm and the reward mentioned for fasting it, our Sheikh Muhammad ibn al-Hasan (may Allah سبحانه وتعالى be pleased with him) did not authenticate it. He stated that it comes through Muhammad ibn Musa al-Hamdani, who was a liar and untrustworthy. Any report that our Sheikh (may Allah سبحانه وتعالى sanctify his soul) did not authenticate or deem correct is, in our view, to be discarded and considered unreliable.
