8. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Hassan from certain individuals of our people who have said the following: “I was present when abu al-Hassan the 1st, Harun, the Caliph, ‘Isa ibn Ja’far and Ja’far ibn Yahya came to al-Madinah to visit the grave of the Holy Prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause. Harun said to abu al-Hassan , ‘You go first.’ He (the Imam) abstained. Harun then moved forward, offered al- Salam and then moved to one side. ‘Isa ibn Ja’far then said to abu al-Hassan , ‘You go first.’ He (the Imam) abstained. ‘Isa then moved forward and offered al-Salam and then moved to one side alongside Harun. Ja’far then said to abu al-Hassan , ‘You go first.’ He (the Imam) abstained. Ja’far then moved forward, offered al-Salam, and then moved to one side alongside Harun. Abu al-Hassan , then moved forward and said, ‘(I hereby declare, affirm and acknowledge that you are a ‘Alayhi al-Salam and my) submission to (your commandments) O my father. I appeal before Allah, who chose you, selected you, guided you and guided through you to grant salawat (favors and compensation to you worthy of Your services to Allah’s cause).’ Harun said to ‘Isa, ‘Did you hear what he said?’ He replied, ‘Yes, I heard what he said.’ Harun then said, ‘I testify that he (the Messenger of Allah) is indeed his father.’”
