What Suffices for Hajjata al-Islam and What Does Not Suffice? (The following Chapter is best explained by fatwa).

8. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from Shihab who has said the following: “A man set free his slave in the evening of the day of ‘Arafah (ninth of Dhul Hajjah); if the slave’s al- Hajj is sufficient for Hajjahta al-Islam. He (the Imam) said, ‘No, it is not sufficient.’ I then asked, ‘Will he receive any reward for it?’ He (the Imam) said, ‘Yes, he receives rewards.’ I asked about a ten-years old boy and his al-Hajj. He (the Imam) عليه السلام, said, ‘He owes Hajjahta al-Islam when he grows to adulthood and so also is the case of a young girl.’”
